Запишите в виде неправильной дроби смешанное число 8целых 2/3, 9целых 1/7 ; 10целых 2/13;...

1.
$8 \frac{2}{3} = \frac{26}{3}$

$9 \frac{1}{7} = \frac{64}{7}$

$10 \frac{2}{13} = \frac{132}{13}$

$101 \frac{1}{6} = \frac{607}{6}$

2.

$\frac{5}{7} < \frac{7}{5}$

$\frac{11}{20} < \frac{20}{11}$

$\frac{123}{400} < \frac{400}{123}$

$\frac{5}{7} \times \frac{7}{5} = \frac{5 \times 7}{7 \times 5} = \frac{1}{1} = 1$

$\frac{11}{20} \times \frac{20}{11} = \frac{11 \times 20}{20 \times 11} = \frac{1}{1} = 1$

$\frac{123}{400} \times \frac{400}{123} = \frac{123 \times 400}{400 \times 123} = \frac{1}{1} = 1$
