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

\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
