Answer 1

Ответ:

$1) \: \frac{2}{7} x = 1 \\ x = 1 \div \frac{2}{7} = 1 \times \frac{7}{2} = \frac{7}{2} \\ x = \frac{7}{2} = 3.5$

$2) \: 9x = 1 \\ x = \frac{1}{9}$

$1 \frac{5}{8} x = 1 \\ x = 1 \div 1 \frac{5}{8} = 1 \div \frac{13}{8} = 1 \times \frac{8}{13} = \frac{13}{8} \\ x = \frac{13}{8}$

$4) \: \frac{1}{2} x = 1 \\ x = 1 \div \frac{1}{2} = 1 \times 2 = 2 \\ x = 2$

$5) \: \frac{7}{15}x = 1 \\ x = 1 \div \frac{7}{15} = 1 \times \frac{15}{7} = \frac{15}{7} \\ x = \frac{15}{7} = 2 \frac{1}{7}$

$6) \: 3 \frac{2}{5} x = 1 \\ \frac{17}{5} x = 1 \\ x = 1 \div \frac{17}{5} = 1 \times \frac{5}{17} \\ x = \frac{5}{17}$

$7) \: 100x = 1 \\ x = \frac{1}{100}$

$8) \: \frac{2}{13} x = 1 \\ x = 1 \div \frac{2}{13} = 1 \times \frac{13}{2} = \frac{13}{2} \\ x = \frac{13}{2} = 6.5$
