Question

Решите пример:
1 целая 1/9*(3 целых 2/3 :1 целая 1/9)

Answer 1

1 1/9 × 3 2/3 = 1 + 1·9/9 × 2 + 3·3/3 = 10/9 × 11/3 = 10·11/9·3 = 110/27 = 2 + 4·27/27 = 4 2/27 4 2/27 ÷ 1 1/9 = 2 + 4·27/27 ÷ 1 + 1·9/9 = 110/27 ÷ 10/9 = 110/27 × 9/10 = 110·9/27·10 = 990/270 = 11·90/3·90 = 11/3 = 2 + 3·3/3 = 3 2/3
