Answer 1

$1 - \frac{2}{7} = \frac{7}{7} - \frac{2}{7} = \frac{5}{7}$

$8 - 3 \frac{6}{9} = 7 \frac{9}{9} - 3 \frac{6}{9} = 4 \frac{3}{9} = 4 \frac{1}{3}$

$3 \frac{2}{8} - 1 \frac{5}{8} = 2 \frac{10}{8} - 1 \frac{5}{8} = 1 \frac{5}{8}$

Answer 2

Ответ:

$1) \frac{5}{7}$

$2)4 \frac{1}{3}$

$3)1 \frac{5}{8}$

Пошаговое объяснение:

$1 - \frac{2}{7} = \frac{7 - 2}{7} = \frac{5}{7}$

$8 - 3 \frac{6}{9} = 8 - \frac{33}{9} = \frac{13}{3} = 4 \frac{1}{3}$

$3 \frac{2}{8} - 1 \frac{5}{8} = \frac{26}{8} - \frac{13}{8} = \frac{13}{8} = 1 \frac{5}{8}$
