Money: pounds and pence
In the UK we use pounds (£) and pence (p). 100 pence make 1 pound. These are the coins: 1p, 2p, 5p, 10p, 20p, 50p, £1 and £2.
And these are the notes: £5, £10, £20 and £50.
Writing money. Money is a decimal. The pounds go before the decimal point and the pence go after it, with two digits. Three pounds and five pence is £3.05, not £3.5 (that would be £3.50). Forty-five pence can be written as 45p or as £0.45. Never write both a £ sign and a p, like £0.45p.
Changing between pounds and pence. To change pounds to pence, multiply by 100: £2.07 = 207p. To change pence to pounds, divide by 100 (the digits move two places to the right, as in Section 6.4): 345p = £3.45. 7p = £0.07 (you need the 0 in the tenths place).
Adding up coins. Count how much each kind of coin is worth in pence, then add the amounts.
Comparing money. To compare amounts, change them to the same unit first. £3.40 and 304p: £3.40 = 340p. 340p is more than 304p, so £3.40 > 304p. Fewest coins. To make an amount with the fewest coins, take the biggest coin that fits, then the biggest coin that fits what is left, and so on.
Key words. Pence (p) are small amounts of money. Pounds (£) are bigger. Change to a different unit means to write the same amount in another unit.
Key ideas
- 100p = £1.
- Money has two digits after the decimal point: £3.05, £4.50.
- Pence to pounds: divide by 100. Pounds to pence: multiply by 100.
- 7p = £0.07, not £0.7. And £4.5 should be £4.50.
- Never write £ and p together.
- To compare money, change everything to pence first.
Key words. Pence (p) are small amounts of money: 100p = £1. Change is the money you get back when you pay with more than the cost. The total is all the amounts added together.
Method. Count how much each kind of coin or note is worth in pence. Add the amounts. Then write the total in pounds and pence.
- Count each kind of note and coin. Group the same ones together. Change each group into pence.1 × £1 = 100p
1 × 50p = 50p
2 × 20p = 40p
1 × 10p = 10p
1 × 5p = 5p
1 × 2p = 2p - Add the groups, biggest first. Adding the big amounts first is easier. Keep a running total.100p
100p + 50p = 150p
150p + 40p = 190p
190p + 10p = 200p
200p + 5p = 205p
205p + 2p = 207p - Write the total. 100p = £1, so change to pounds and pence if it is 100p or more.207p = £2.07
Check. Add in a different order, smallest first: 2p + 5p + 10p + 20p + 20p + 50p + 100p = 207p. ✓
Watch out. Change everything to pence first. Do not add pounds and pence together as if they were the same.
Key words. Pence (p) are small amounts of money: 100p = £1. Change is the money you get back when you pay with more than the cost. The total is all the amounts added together.
Method. Divide the pence by 100 to find the pounds. The pence left over go after the decimal point, with two digits.
- Remember: 100 pence make 1 pound. So we divide the pence by 100 to find the pounds.345 ÷ 100 = 3 remainder 45
- Write the pounds and the pence. 3 pounds and 45p.3 pounds and 45p
- Put them together with a decimal point. The pence always get two digits after the decimal point.£3.45
Check. Go back: £3.45 = 3 × 100 + 45 = 345p. ✓
Watch out. Money always has two digits after the decimal point.
Key words. Pence (p) are small amounts of money: 100p = £1. Change is the money you get back when you pay with more than the cost. The total is all the amounts added together.
Method. Divide the pence by 100 to find the pounds. The pence left over go after the decimal point, with two digits.
- Remember: 100 pence make 1 pound. So we divide the pence by 100 to find the pounds.7 ÷ 100 = 0 remainder 7
- Write the pounds and the pence. The amount is less than 100p, so there are no whole pounds.0 pounds and 7p
- Put them together with a decimal point. The pence always get TWO digits: write a 0 in front if there is only one.£0.07 (the 0 holds the tens-of-pence place)
Check. Go back: £0.07 = 0 × 100 + 7 = 7p. ✓
Watch out. Do not write £0.7: money always has two digits after the point.
Key words. Pence (p) are small amounts of money: 100p = £1. Change is the money you get back when you pay with more than the cost. The total is all the amounts added together.
Method. Multiply the pounds by 100 and add the pence.
- Remember: 1 pound is 100 pence. So we multiply the pounds by 100.2 × 100 = 200p
- Add the pence. The two digits after the decimal point are the pence.200p + 7p = 207p
- Write the answer with the unit p. Pence are written with a small p after the number.£2.07 = 207p
Check. Go back: 207p ÷ 100 = £2.07. ✓
Watch out. £2.07 is 207p, not 27p: if the pence are less than 10, put a 0 in: £2.07 = 207p.
Key words. Pence (p) are small amounts of money: 100p = £1. Change is the money you get back when you pay with more than the cost. The total is all the amounts added together.
Method. Change both amounts into the same unit (pence). Then compare the numbers.
- Change both amounts to pence. We can only compare money when it is in the same unit. To change pounds to pence, multiply by 100.£3.40 = 340p (£3 × 100 + 40 = 340)
304p = 304p - Compare the numbers of pence. The bigger number of pence is the bigger amount.340 > 304
- Write the answer. £3.40 > 304p
Check. Picture £3.40 and 304p as coins: more money in the first. ✓
Watch out. Do not compare 3.40 with 304 as they are. Change to the same unit first: 340p and 304p.
Key words. Pence (p) are small amounts of money: 100p = £1. Change is the money you get back when you pay with more than the cost. The total is all the amounts added together.
Method. Change every amount to pence. Put the numbers in order. Then write the amounts the way they were first written.
- Change every amount to pence. The amounts are in different units, so we change them all to pence (£1 = 100p).£1.20 = 120p
95p = 95p
£1.05 = 105p
110p = 110p - Put the numbers of pence in order. We want smallest first.95p, 105p, 110p, 120p
- Write the original amounts in that order. Use the way each amount was written in the question.95p, £1.05, 110p, £1.20
Check. Count them: 4 amounts in the question and 4 in the answer. ✓
Watch out. Do not mix up pence and pounds: 95p is less than £1.05 even though 95 is bigger than 1.05.
Key words. Pence (p) are small amounts of money: 100p = £1. Change is the money you get back when you pay with more than the cost. The total is all the amounts added together.
Method. Start with the biggest coin that fits. Take it away, then do the same with what is left. Keep going until nothing is left.
- Take the biggest coin that is not more than 187p. Using the biggest coins each time gives the fewest coins.Take £1. 187p − 100p = 87p left
- Take the biggest coin that is not more than 87p. Using the biggest coins each time gives the fewest coins.Take 50p. 87p − 50p = 37p left
- Take the biggest coin that is not more than 37p. Using the biggest coins each time gives the fewest coins.Take 20p. 37p − 20p = 17p left
- Take the biggest coin that is not more than 17p. Using the biggest coins each time gives the fewest coins.Take 10p. 17p − 10p = 7p left
- Take the biggest coin that is not more than 7p. Using the biggest coins each time gives the fewest coins.Take 5p. 7p − 5p = 2p left
- Take the biggest coin that is not more than 2p. Using the biggest coins each time gives the fewest coins.Take 2p. 2p − 2p = 0p left
- Write the coins. Check the amount: they should add up to £1.87.£1, 50p, 20p, 10p, 5p, 2p (6 coins)
Check. Add the coins: 100p + 50p + 20p + 10p + 5p + 2p = 187p = £1.87. ✓
Watch out. Do not use lots of small coins. Always take the biggest coin that fits.
Watch out
Two digits for the pence. £5.05 is 5 pounds and 5 pence. £5.5 would mean £5.50. And when you compare, do not compare 95 with 1.05 as they are: change to the same unit. 95p is LESS than £1.05 even though 95 is a bigger number than 1.05.Exercise 6F Money: pounds and pence

Method. Pence need two digits. Single-digit pence need a 0 in front.
- Look at what Amira wrote. Amira wrote 5 pence after the point as a single digit.£5.5 means 5 pounds and 50p, which is £5.50.
- Think about the pence. 5p is less than 10p. The tens-of-pence place needs a 0.0 tens of pence and 5 pence
- Write it correctly. Two digits for the pence: 0 then 5.£5.5 → £5.05
Check. Say it in words: £5.05 is 5 pounds and 5 pence. ✓
Watch out. £5.5 is £5.50. For 5p you must write £5.05.
Key words. Pence (p) are small amounts of money: 100p = £1. Change is the money you get back when you pay with more than the cost. The total is all the amounts added together.
Method. Use the pound sign with a decimal point, OR the p sign. Never both.
- Look at what Amira wrote. Look at the signs.£0.45p has a pound sign AND a p.
- Think about the symbols. The pound sign and the decimal point already say these are pounds. The p says pence. We only use one of them.£0.45 means 45 pence, and 45p also means 45 pence.
- Write it correctly. Use either pounds or pence.£0.45 or 45p
Check. £0.45 is 45 pence. ✓
Watch out. Never write both £ and p together.
Key words. Pence (p) are small amounts of money: 100p = £1. Change is the money you get back when you pay with more than the cost. The total is all the amounts added together.
Method. Money needs two digits after the decimal point. Add a 0 on the end.
- Look at what Amira wrote. Count the digits after the decimal point.£20.3 has only one digit after the point.

Method. Count how much each kind of coin or note is worth in pence. Add the amounts. Then write the total in pounds and pence.
- Count each kind of note and coin. Group the same ones together. Change each group into pence.2 × £1 = 200p
3 × 50p = 150p
5 × 20p = 100p
4 × 10p = 40p - Add the groups, biggest first. Adding the big amounts first is easier. Keep a running total.200p

Method. Find five coins that add up to 100p. Try a big coin first, then fill the gap.
- Way 1: start with 50p. That leaves 50p for 4 coins. 20p + 10p + 10p + 10p = 50p.50p + 20p + 10p + 10p + 10p = 100p
- Way 2: start with 50p again but use different coins. 50p is left for 4 coins. 20p + 20p + 5p + 5p = 50p.50p + 20p + 20p + 5p + 5p = 100p
- Way 3: use only one kind of coin. 100p ÷ 5 = 20p, so five 20p coins.20p + 20p + 20p + 20p + 20p = 100p
Check. Each way uses 5 coins and the total is 100p = £1. ✓
Watch out. There are other correct ways. Check every one adds up to 100p and uses exactly 5 coins.
