Question

Помагите решить математику, делать по действиям и сокращять Сразу

Answer 1

1) 6 6/11 = 6*11+6 = 72/11

2) 2 2/5 = 2*5+2 = 12/5

3) 2 1/5 = 2*5+1 = 11/5

4)

$\frac{72}{11} \times \frac{3}{4} = \frac{72 \times 3}{11 \times 4} = \frac{18 \times 3}{11} = \frac{54}{11}$

5)

$\frac{54}{11} \div \frac{12}{5} = \frac{54 \times 5}{11 \times 12} = \frac{27 \times 5}{11 \times 6} = \frac{135}{66}$

6)

$\frac{135}{66} \times \frac{11}{5} = \frac{135 \times 11}{66 \times 5} = \frac{135}{6 \times 5} = \frac{27}{6} = \frac{9}{2} = 4 \frac{1}{2} = 4.5$

ответ: 4.5
