Tina lives 2 1/4 miles from the library Sonya lives 3 1/2 miles from the library how much further does Sonya live then Tina

1 1/4 miles

Step-by-step explanation:

3 1/2 = 7/2

2 1/4 = 9/4

7/2 - 9/4 = ?

To do this, we need common denominator. The lowest we can do is 4.

7/2 * 2/2 = 14/4

14/4 - 9/4 = 5/4

5/4 can also be written 1 1/4
