24. 4/12 X 9/12 = 36/144 reduced 1/4
I would reduce from the beginning to look like:
1/3 X 3/4 = 3/12 reduced 1/4

25. 5/8 x 32 = 20 had cell phones; 3/4 of 20 = 15 people had music devices

26. Audrey ate 1/16 of 32 = 2 pieces
Class ate 3/4 of 32 = 24 pieces
so there is now 6 pieces remaining in which the brothers would eat 1/3 each, so 1/3 of 6 is equal to 2 pieces each.
