Add these fractions. First strategy: find a common denominator. You can do this by looking at the smallest denominator and seeing if it will go into the larger denominator evenly. Second strategy: multiply the two denominators together.

13. 3 1/9 x 2 6/9 =
(9 should be your
Common denominator) 3 1/9
6 6/9

14. 4 2/5 x 2 1/6 = 4 2/5
(30 should be your +2 1/6
common denominator)

15. 2 4/5 x 6 7/25 = 2 4/5
(25 should be your common +6 7/25
denominator)
