Metres and centimetres (focused practice) worksheet: Answers and working

1. 509 cm = 5 m 9 cm
509 cm: 5 m is 5 × 100 = 500 cm, 509 − 500 = 9
2. 905 cm = 9 m 5 cm
905 cm: take off the 5 cm first, 905 − 5 = 900, 900 ÷ 100 = 9
3. 3 m 9 cm = 309 cm
3 m 9 cm: 1 m = 100 cm, 3 × 100 = 300, 300 + 9 = 309
4. 2 m 88 cm = 288 cm
2 m 88 cm: 1 m = 100 cm, 2 × 100 = 200, 200 + 88 = 288
5. 700 cm = 7 m
700 cm: 1 m = 100 cm, 700 ÷ 100 = 7
6. 615 cm = 6 m 15 cm
615 cm: take off the 15 cm first, 615 − 15 = 600, 600 ÷ 100 = 6
7. 500 cm = 5 m
500 cm: 1 m = 100 cm, 500 ÷ 100 = 5
8. 792 cm = 7 m 92 cm
792 cm: 7 m is 7 × 100 = 700 cm, 792 − 700 = 92
9. 8 m 14 cm = 814 cm
8 m 14 cm: 1 m = 100 cm, 8 × 100 = 800, 800 + 14 = 814
10. 263 cm = 2 m 63 cm
263 cm: 2 m is 2 × 100 = 200 cm, 263 − 200 = 63
11. 5 m 34 cm = 534 cm
5 m 34 cm: 1 m = 100 cm, 5 × 100 = 500, 500 + 34 = 534
12. 565 cm = 5 m 65 cm
565 cm: 5 m is 5 × 100 = 500 cm, 565 − 500 = 65

13. In the long jump, Chi-keung jumped 154 cm and Ming jumped 1 m 74 cm. How many centimetres further did Ming jump than Chi-keung? (Answer: 20 cm)
100 × 1 + 74 = 174; 100 × 1 + 74 − 154 = 20
14. In the long jump, May jumped 152 cm and Ming jumped 2 m 53 cm. How many centimetres further did Ming jump than May? (Answer: 101 cm)
100 × 2 + 53 = 253; 100 × 2 + 53 − 152 = 101
15. A roll of ribbon is 8 m long. After 50 cm is cut off, how many centimetres are left? (Answer: 750 cm)
100 × 8 = 800; 100 × 8 − 50 = 750
16. A skipping rope is 8 m 5 cm long. How long is it in centimetres? (Answer: 805 cm)
100 × 8 + 5 = 805
17. A roll of ribbon is 2 m long. After 50 cm is cut off, how many centimetres are left? (Answer: 150 cm)
100 × 2 = 200; 100 × 2 − 50 = 150
18. Chi-keung is 135 cm tall, 9 cm shorter than Tsz-hin. How tall is Tsz-hin, in centimetres? (Answer: 144 cm)
135 + 9 = 144
