Question

Решите уравнение

х: 2 2/3 = 1,5*2/9

Answer 1

$x \div 2 \frac{2}{3} = 1.5 \times \frac{2}{9} \\ x \div \frac{8}{3} = \frac{3}{2} \times \frac{2}{9} \\ x \times \frac{3}{8} = \frac{3 \times 2}{2 \times 9} \\ \frac{3x}{8} = \frac{1}{3} \\ 3 \times 3x = 1 \times 8 \\ 9x = 8 \\ x = \frac{8}{9}$

Ответ: х = 8/9
