Срочноооо

Answer 1

$\frac{9}{8} \div \frac{3}{4} = \frac{9 \times 4}{8 \times 3} = \frac{3 \times 1}{2 \times 1} = \frac{3}{2} = 1 \frac{1}{2} = 1.5$

$\frac{6}{7} \div \frac{3}{14} = \frac{6 \times 14}{7 \times 3} = \frac{2 \times 2}{1 \times 1} = 4$

$\frac{25}{27} \div \frac{5}{9} = \frac{25 \times 9}{27 \times 5} = \frac{5 \times 1}{3 \times 1} = \frac{5}{3} = 1\frac{2}{3}$

$\frac{4}{15} \div \frac{12}{35} = \frac{4 \times 35}{15 \times 12} = \frac{1 \times 7}{3 \times 3} = \frac{7}{9}$
