Answer 2

$\frac{1}{3}- \frac{1}{5}= \frac{5-3}{15}= \frac{2}{15} \\ \\ \frac{3}{5}- \frac{1}{7}= \frac{21-5}{35}= \frac{16}{35} \\ \\ \frac{1}{3}- \frac{1}{6}= \frac{2-1}{6}=\frac{1}{6}\\ \\ \frac{9}{14}- \frac{2}{7}= \frac{9-4}{14}= \frac{5}{14} \\ \\ \frac{5}{6}- \frac{3}{8}= \frac{20-9}{24}= \frac{11}{24} \\ \\ \frac{9}{14}- \frac{9}{21}= \frac{27-18}{42}= \frac{9}{42}= \frac{3}{14}$
