Пошаговое объяснение:
решение на фото.................
5 17/20 + (3 1/2 - 2 3/8) * 1 1/3 * (4 1/3 - 1 1/5) = 10 11/20,
1) 3 1/2 - 2 3/8 = 3 4/8 - 2 3/8 = 1 1/8,
2) 4 1/3 - 1 1/5 = 4 5/15 - 1 3/15 = 3 2/15,
3) 1 1/8 * 1 1/3 * 3 2/15 = 9/8 * 4/3 * 47/15 = 47/10 = 4 7/10,
4) 5 17/20 + 4 7/10 = 5 17/20 + 4 14/20 = 9 31/20 = 10 11/20
