Question

-1 1/9х=5/6
P.S / дроб​

Answer 1

Ответ:

$x = \frac{3}{4}$

Пошаговое объяснение:

$- 1 \frac{1}{9} x = \frac{5}{6}$

$\frac{10}{9} x = \frac{5}{6}$

$x = \frac{9}{10} \times \frac{10}{9} x = \frac{9}{10} \times \frac{5}{6}$

$x = \frac{3}{2} \times \frac{1}{2}$

$x = \frac{3}{4}$

Проверка:

_________________________

$- \frac{10}{9} \times \frac{3}{4} = \frac{5}{6}$

$\frac{5}{6} = \frac{5}{6}$

Answer 2

$- 1 \frac{1}{9} x = \frac{5}{6} \\ x = \frac{5}{6} \div ( - 1 \frac{1}{9} ) \\ x = - \frac{5 \times 9}{6 \times 10} \\ x = - \frac{1 \times 3}{2 \times 2} \\ x = - \frac{3}{4} \\ x = - 0.75$
