Accepted Answer

\(\frac{5}{6}-\frac{1}{4}=\frac{10}{12}-\frac{3}{12}=\frac{7}{12}\).
\(\frac{7}{10}-\frac{3}{5}=\frac{7}{10}-\frac{6}{10}=\frac{1}{10}\).
\(\frac{9}{14}-\frac{1}{7}=\frac{9}{14}-\frac{2}{14}=\frac{7}{14}=\frac{1}{2}\).
\(\frac{11}{12}-\frac{5}{8}=\frac{22}{24}-\frac{15}{24}=\frac{7}{24}\).
\(\frac{13}{18}-\frac{1}{6}=\frac{13}{18}-\frac{3}{18}=\frac{10}{18}=\frac{5}{9}\).
\(\frac{3}{5}-\frac{1}{10}=\frac{6}{10}-\frac{1}{10}=\frac{1}{2}\).
\(\frac{7}{9}-\frac{2}{3}=\frac{7}{9}-\frac{6}{9}=\frac{1}{9}\).
\(\frac{4}{15}-\frac{1}{5}=\frac{4}{15}-\frac{3}{15}=\frac{1}{15}\).
\(\frac{5}{8}-\frac{3}{16}=\frac{10}{16}-\frac{3}{16}=\frac{7}{16}\).
\(\frac{17}{24}-\frac{5}{12}=\frac{17}{24}-\frac{10}{24}=\frac{7}{24}\).
