Пошаговое объяснение:
11) = 5 1/4 * (8 3/17 + 3 14/17) = 5 1/4 * 12 = 21/4 * 12 = 21 * 3 = 63
12) = 3 4/13 * ( 15 3/41 - 2 3/41) = 3 4/13 * 13 = 43/13 * 13 = 43
13) = (11/4 + 33/8) * 16/11 = 4 + 6 = 10
14) = 7/5 * ( 15/14 - 5/7) = 3/2 - 1 = 1/2
15) = 25/4 * 8 - 11/3 * 11/2 + 12/5 * 55/12 = 50 - 121/6 + 11 = 61 - 20 1/6 = 40 5/6
16) = (3 15/30 - 2 20/30 + 5 25/30 + 4 18/30) *24 = 10 38/30 * 24 = 11 4/15 * 24 = 169/15 * 24 = 169/5 * 8 = 1352/5 = 270 2/5
