24/13 - 9/13 = (24 - 9)/13 =15/13
13 out of 24 is 54.17%
24 * 13 = 312
24/13 = 111/13
24/13 = 111/13
37/24 = 1 13/24
-13 + 24 = 11
11 - 24 = -13
7/8 + 13/24 = (7*3)/(8*3) + 13/24 = 21/24 + 13/24 = 34/24 = 17/12 or 1 5/12
One possibility is (21 - 21) * 13 + 24 = 24
13 / 24 = 54.17%
24% of 13 = 3.12 or 312%
