3 4/9 *(1 3/5 х - 0.4)= 2 1/3

Answer 1

Ответ:

$3 \frac{4}{9} \times (1 \frac{3}{5}x - 0.4) = 2 \frac{1}{3} \\ \frac{31}{9} ( \frac{8}{5} x - \frac{2}{5} ) = \frac{7}{3} \\ \frac{ 248}{45} x - \frac{62}{45} = \frac{7}{3} \\ 248x - 62 = 105 \\ 248x = 105 + 62 \\ 248x = 167 \\ x = 167 \div 248 \\ x = \frac{167}{248}$
