Question

15/20 + 12 /20 = 27/20 =

Answer 1

1 7/20

Explanation:

So, you added the 15/20 and 12/20 to get 27/20

Then to simplify 27/20 you have to see how many times 27 can go into 20

27 can go into 20 with a remainder of 7 which then will lead you to the answer of 1 7/20 and you can't simplify it anymore.

Hopefully, that helps.
