32 (1.1/4-7/32) = напишите решение

32 * (1 1/4 - 7/32) = 33.

1) 1 1/4 - 7/32 = 1 + 1/4 - 7/32 = 1 + (1 * 8) / (4 * 8) - 7/32 = 1 + 8/32 - 7/32 = 1 + (8 - 7) / 32 = 1 + 1/32 = 1 1/32;

2) 32 * 1 1/32 = 32 * (1 * 32 + 1) / 32 = 32 * (32 + 1) / 32 = 32 * 33/32 = (32 * 33) / 32 = 33.

Решим подобный пример:

15 * (2 2/5 - 1 4/15) = 17.

1) 2 2/5 - 1 4/15 = 2 - 1 + 2/5 - 4/15 = 1 + (2 * 3) / (5 * 3) - 4/15 = 1 + 6/15 - 4/15 = 1 + (6 - 4) / 15 = 1 + 2/15 = 1 2/15;

2) 15 * 1 2/15 = 15 * (1 * 15 + 2) / 15 = 15 * (15 + 2) / 15 = 15 * 17/15 = (15 * 17) / 15 = 17.
