1)3-1/32)7-3/43)7-3 7/94)7-5 4/105)1-20/306)1-2/7

Answer 1

1) $\frac{3}{1} - \frac{1}{3} = \frac{9 - 1}{3} = \frac{8}{3} = 2\frac{2}{3}$
2) $7 - \frac{3}{4} = 6 \frac{1}{4}$
3) $7 - 3\frac{7}{9} = \frac{7}{1} - \frac{34}{9} = 3 \frac{2}{9}$
4) $7 - 5 \frac{4}{10} = 1 \frac{3}{5}$
5) $\frac{1}{1} - \frac{20}{30} = \frac{1}{1} - \frac{2}{3} = \frac{1}{3}$
6) $\frac{1}{1} - \frac{2}{7} = \frac{7 - 2}{7} = \frac{5}{7}$
Надеюсь, помог
