Answer 2

Step-by-step explanation:

$(a) \: \frac{6}{7} \div \frac{9}{5}$

$= \frac{6}{7} \times \frac{5}{9}$

$= \frac{6 \times 5}{7 \times 9}$

$= \frac{2 \times 5}{7 \times 3}$

$= \frac{10}{21} (ans)$

$(b) \: \frac{12}{5} \div \frac{15}{4}$

$= \frac{12}{5} \times \frac{4}{15}$

$= \frac{12 \times 4}{5 \times 15}$

$= \frac{4 \times 4}{5 \times 5}$

$= \frac{16}{25} (ans)$

$(c) \: 2 \frac{5}{7} \div \frac{19}{14}$

$= \frac{19}{7} \div \frac{19}{14}$

$= \frac{19}{7} \times \frac{14}{19}$

$= \frac{19 \times 14}{7 \times 19}$

$= \frac{1 \times 2}{1 \times 1}$

= 2 (Ans)
