Answer 1

The chameleon grew .94 inches, and would need to grow .64 inches to be exactly 10 inches.

Answer 2

This is easy, Answer to A is 0.91 because 9.36-8.45=0.91

Answer to B is 0.64 because 10.00 (add the decimal to the end to make it easier to subtract) 10.00-9.36=0.64 (use 9.36 because its his hight now)
