Exercise 8Z Check-up
Non-calculatorMethod. A shape is split into halves only when there are 2 equal parts.
- Count the parts. We need 2 equal parts to be halves.2 parts
- Check the parts are the same size. Equal parts must be the same size.the parts are not equal
- Write the answer. The parts are not all the same size, so it is not split into equal parts.no

Exercise 8X Practice test questions
Non-calculatorMethod. Divide the number into equal parts, then take the number of parts the fraction says.
- Split 28 into 4 equal groups. Each group is one part of the whole.28 ÷ 4 = 7
- Take 1 of the groups. 1/4 means 1 of the 4 equal parts.1 × 7 = 7
- Write the answer. This is the amount for the fraction.7
Check. Check: 7 is 1 of the 4 equal groups of 7.
Watch out. The bottom number tells you how many equal groups to split into. The top number tells you how many to take.
Method. Count the equal parts for the bottom number, and the shaded parts for the top number.
- Count the equal parts. The shape is split into 4 equal parts.4 equal parts
- Count the shaded parts. 2 of the 4 parts are shaded.2 shaded
