Remember the MAD method.

A dd

D enominator the same

1/10 + 1/5 + 1/2

Make common denominators (number on bottom) (10 in this case).

What is done to the bottom must be done to the top.

5 x 2 = 10; 1 x 2 = 2 2 x 5 = 10; 1 x 5 = 5

1/10 + 2/10 + 5/10

Add numerators (number on top).

1 + 2 + 5 = 8

Keep the denominator the same.

8/10

Simplify.

8 and 10 can both be divided by 2.

8 / 2 = 4; 10 / 2 = 5

4/5

Answer: She sent 4/5 of an hour doing the activities.
