Answer 1

Ответ:

Пошаговое объяснение:

2/5:3/10=2/5*10/3=4/3=1 1/3

21/34:7=21/34*1/7=3/34

2,2/7:2,2/3=16/7*3/8=6/7

Answer 2

$\frac{2}{5} \div \frac{3}{10} = \frac{2}{5} \times \frac{10}{3} = \frac{4}{3 } = 1\frac{1}{3}$

$\frac{21}{34} \div 7 = \frac{21}{34} \times \frac{1}{7} = \frac{3}{34}$

$\frac{2,2}{7} \div \frac{2,2}{3} = \frac{16}{7} \times \frac{3}{8} = \frac{6}{7}$
