Question

А)3/5х=1 б)3/7х=1/2 в)5/6х=2/3
Пж поиогите дам 50 балов

Answer 1

$\frac{3}{5} x = 1 \\ x = 1 \div \frac{3}{5} \\ x = \frac{5}{3} \\ x = 1 \frac{2}{3}$

$\frac{3}{7} x = \frac{1}{2} \\ x = \frac{1}{2} \div \frac{3}{7} \\ x = \frac{7}{2 \times 3} \\ x = \frac{7}{6} \\ x = 1 \frac{1}{6}$

$\frac{5}{6} x = \frac{2}{3} \\ x = \frac{2}{3} \div \frac{5}{6} \\ x = \frac{2 \times 6}{3 \times 5} \\ x = \frac{2 \times 2}{ 1\times 5} \\ x = \frac{4}{5} \\ x = 0.8$

Answer 2

Пошаговое объяснение:

3/5х = 1

х = 1 : 3/5

х = 1 * 5/3

х = 5/3

х = 1 2/3

3/7х = 1/2

х = 1/2 : 3/7

х = 1/2 * 7/3

х = 7/6

х = 1 1/6

5/6х = 2/3

х = 2/3 : 5/6

х = 2/3 * 6/5

х = 12/15

х = 4/5
