You mow 1/3 of the lawn. Your sister mows 2/5 of the lawn. What fraction of the lawn is left to mow?​

11/15

Step-by-step explanation:

YOu're gonna have to add the fractions together but since the denominators are different, you're gonna have to mutiply to find a common denominator. 15 is a common denominator between 3 and 5 so that's what I'll be using.

1/3 x 5/5 = 5/15    2/5 x 3/3 = 6/15

Since they now have common denominators, you can add them.

5/15 + 6/15 = 11/15
