Question

Вычислите:7 1/3:1 2/9+4 8/9*9/11

Answer 1

$7\frac{1}{3}:1\frac{2}{9}+4\frac{8}{9}*\frac{9}{11}=\frac{22}{3}:\frac{11}{9}+\frac{44}{9}*\frac{9}{11}=\frac{22}{3}*\frac{9}{11}+4=2*3+4=6+4=10$

Answer 2

7 1/3 : 1 2/9 + 4 8/9 · 9/11 = 10

1) 7 1/3 : 1 2/9 = 22/3 : 11/9 = 22/3 · 9/11 = (2·3)/(1·1) = 6

2) 4 8/9 · 9/11 = 44/9 · 9/11 = (4·1)/(1·1) = 4

3) 6 + 4 = 10

Ответ: 10.
