Answer 1

2/10 , 3/15 , 4/20, 5/25

Those are some examples.

Answer 2

Oh those are easy, but remember this, every time you do fraction it doubles. So for example: 1/2 it's one half, now watch: 2/4 see what I did there? I halved it again. It so simple, all you have to do is times it by to all the time, and when you get to an odd number like 1 3 5 7 etc... You will know then you passed it, that is for dividing, but for multiplying you just have to multiply by 2, and by dividing you divide it by 2, if you still don't reach your answer, keep dividing by 2 till you get to one of the odd numbers. Simple as that.
