Roi had some milk.He drank 1/3 and gave the 2/5 of the remainder to his sister.What fraction of the milk was left?

Question

I dont understand on how to do this question

Answer 1

First:  he drank 1/3, so 1 - 1/3 = 2/3 is the remainder.

Second, he gave away 2/5 of the remainder, so 3/5 of the remainder was left.  3/5 of 2/3 is 3/5 * 2/3 

You can go from here!
