Answer 2

Ответ:

$\frac{2}{3} \div \frac{7}{9} = \frac{2}{3} \times \frac{9}{7} = \frac{6}{7}$

$6 \div \frac{3}{5} = 6 \times \frac{5}{3} = 10$

$4 \frac{1}{2} \div 3 \frac{3}{4} = \frac{9}{2} \div \frac{15}{4} = \frac{9}{2} \times \frac{4}{15} = \frac{6}{5} = 1 \frac{1}{5}$

$\frac{20}{21} \div 15 = \frac{20}{21} \times \frac{1}{15} = \frac{4}{63}$
