Answer 1

Ответ:

$3 \frac{1}{2} x - \frac{1}{4} = 3 \div 8 \\ 3 \frac{1}{2} x - \frac{1}{4} = \frac{3}{8} \\ 3 \frac{1}{2} x = \frac{3}{8} + \frac{1}{4} \\ 3 \frac{1}{2} x = \frac{3}{8} + \frac{2}{8} \\ 3 \frac{1}{2} x = \frac{5}{8}$

$x = \frac{5}{8} \div 3 \frac{1}{2} \\ x = \frac{5}{8} \div \frac{7}{2} = \frac{5}{8} \times \frac{2}{7} \\ x = \frac{5}{28}$
