What is twenty over fifty in simplest form?

Answer 1

2/5

This one is simple since they both end in 0. Zeros can be crossed out.

Ex: 200/500 is the same as 2/5

otherwise find a number that goes into the top number(denominator) and botom number (numerator)

10 goes into 20, 2 times. 10 goes into 50, 5 times.

say you thought the biggest number that could go into both was 5.

5 goes into 20, 4 times. 5 goes into 50, 10 times. This makes it 4/10. You can now see that 2 can go into both of those numbers making the answer 2/5.
