Sure, here are the answers to your questions:

1. Convert into centimetres. a. 2 m = 200 cm b. 4 m = 400 cm c. 90 m = 9000 cm e. 15 m 20 cm = 1520 cm f. 6 m 50 cm = 650 cm g. 12 m 9 cm = 1209 cm d. 70 m 25 cm = 7025 cm b. 8 m 50 cm = 850 cm

2. Convert the following into m and cm. a. 400 cm = 4 m 0 cm b. 306 cm = 3 m 6 cm c. 129 cm = 1 m 29 cm d. 256 cm = 2 m 56 cm e. 781 cm = 7 m 81 cm f. 244 cm = 2 m 44 cm g. 888 cm = 8 m 88 cm h. 413 cm = 4 m 13 cm

3. How many more centimetres are required to make a metre? a. 82 cm = 18 cm more b. 57 cm = 43 cm more c. 9 cm = 91 cm more e. 23 cm = 77 cm more d. 84 cm = 16 cm more f. 49 cm = 51 cm more

Please note that for question 3, I assumed you meant how many more centimetres are needed to reach 100 cm (which is 1 metre).
