по действиям!!​

Answer 1

***

$2\times \left(28\div \:7\right)\div \:6+39-19+\left(6\times \:3\right)\times \:27\div \:9 =$

$2\times \:4\div \:6+39-19+\left(6\times \:3\right)\times \:27\div \:9=$

$2\times \:4\div \:6+39-19+18\times \:27\div \:9=$

$8\div \:6+39-19+18\times \:27\div \:9=$

$\frac{8}{6}+39-19+18\times \:27\div \:9 =$

$\frac{8}{6}+39-19+486\div \:9 =$

$\frac{8}{6}+39-19+54 =$

$\frac{8}{6} +20 + 54 =$

$\frac{64}{3}+54 =$

$\frac{54\times \:3}{3}+\frac{64}{3} =$

$\frac{54\times \:3+64}{3} =$

$\frac{226}{3} =$

$75\frac{1}{3}$

ответ: 75. 1/3
