Question

You have to write 0.63 as a fraction. How do you choose the denominator?

Answer 1

you write .63/1 since all numbers are over one.

Answer 2

You write .63/1 or (63/100) but since you can't really do anything with that, you move the decimals so that it's a whole number but you have to move the decimal the same amount of times with the one. So since you move 2 times so that it's 63, you do the same with the one=100. So the answer is 63/100
