Answer 1

Решение и ответ:

$1 \frac{5}{7} \div 1 \frac{1}{7} = \frac{12}{7} \times \frac{7}{8} = 1.5$

$3 \frac{1}{5} \div 2 \frac{2}{15} = \frac{16}{5} \times \frac{15}{32} = 1.5$

$5 \frac{2}{3} \div \frac{1}{3} - 1 \frac{7}{12} \times 6 = \frac{17}{3} \times 3 - \frac{19}{12} \times 6 = 17 - 9.5 = 7.5$
