1/7: 2/14
6: 8/9
16/7: 12

Answer 1

Explicación paso a paso:

15/9 :3/5

$\frac{15}{9}\div \frac{3}{5} = \frac{15}{9}\times \frac{5}{3} = \frac{15 \times 5}{9 \times 3} = \frac{75}{27} = \frac{25}{9}$

1/7: 2/14

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

6: 8/9

$6\div \frac{8}{9} = 6\times \frac{9}{8} = \frac{6 \times 9}{1 \times 8} = \frac{54}{8} = \frac{27}{4}$

16/7: 12

$\frac{16}{7}\div12 = \frac{16}{7}\times \frac{1}{12} = \frac{16 \times 1}{7 \times 12} = \frac{16}{84} = \frac{4}{21}$
