Answer 1

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