darinaavans · Answer

9 * 4/9 - 1/3 = 4 - 1/3 = 3 3/3 - 1/3 = 3 2/3

8 * 3/16 - 1/8 = 3/2 - 1/8 = 1 1/2 - 1/8 = 1 3/8

10 * 5/8 - 1/4 = 25/4 - 1/4 = 6 1/4 - 1/4 = 6

11 * 7/12 - 1/4 = 77/12 - 1/4 = 6 5/12 - 1/4 = 6 5/12 - 3/12 = 6 2/12 = 6 1/6

13 * 19/36 - 1/9 = 3 - 1/9 = 2 9/9 - 1/9 = 2 8/9

7 * 41/48 - 5/6 = 287/48 - 5/6 = 5 47/48 - 5/6 = 5 7/48
