What is 20/9 in simplest form?

20/9 in simplest form would be 2 2/9

What you would do is see how many times your denominator can go into your numerator. 9 goes into 20 two times. So you would take your two and put it on the outside as a whole number. Then you would take your left over two and make it you numerator. Therefore you will get 2 2/9 as your answer.

HOPE THIS HELPS! ^_^

9 can go into 20 two times and 2 remain out of 9

Ratios can be written 3 ways.  One way is 52:13 and another ways is 52/13.  If you look at it as a fraction, like 52/13 then that can be reduced to 4 but as a ratio would be 4/1.  this can be written 4/1, 4:1, or 4 to 1.  hope this helps
