Question

Before a race, you start 3 1/4 feet behind your friend. At the finish line you are 2 1/3 feet ahead of your friend. What is the change in distance between you and your friend?

Answer 1

11/12 feet

Explanation:

3 1/4 - 2 1/3

4 * 3 = 12

3* 4 = 12

1 * 3 = 3

1 * 4 = 4

3 3/12 - 2 4/12

3 * 12 = 36

12 * 2 = 24

36+ 3 = 39

24 + 4 = 28

39/12 - 28/12 = 11/12
