\(\frac{1}{6}+\frac{1}{27}=\frac{9+2}{54}=\frac{11}{54}\).
\(\frac{7}{8}+\frac{1}{2}=\frac{7}{8}+\frac{4}{8}=\frac{11}{8}=1\frac{3}{8}\).
\(\frac{1}{9}-\frac{1}{27}=\frac{3-1}{27}=\frac{2}{27}\).
\(\frac{5}{26}+\frac{1}{6}=\frac{15+13}{78}=\frac{14}{39}\).
\(\frac{2}{7}+\frac{7}{9}=\frac{18+49}{63}=\frac{67}{63}=1\frac{4}{63}\).
\(\frac{1}{2}-\frac{1}{8}=\frac{3}{8}\).
\(\frac{22}{49}-\frac{2}{7}=\frac{22-14}{49}=\frac{8}{49}\).
\(\frac{5}{7}-\frac{1}{2}=\frac{10-7}{14}=\frac{3}{14}\).
\(\frac{2}{9}-\frac{2}{7}=\frac{14-18}{63}=-\frac{4}{63}\).
\(\frac{1}{10}-\frac{1}{11}=\frac{1}{110}\).
\(\frac{1}{2}+\frac{1}{8}=\frac{5}{8}\).
\(\frac{1}{12}+\frac{1}{3}=\frac{1+4}{12}=\frac{5}{12}\).
\(\frac{2}{8}+\frac{1}{6}=\frac{1}{4}+\frac{1}{6}=\frac{5}{12}\).
\(\frac{6}{6}-\frac{2}{6}=\frac{4}{6}=\frac{2}{3}\).
\(\frac{7}{8}-\frac{1}{2}=\frac{7-4}{8}=\frac{3}{8}\).
\(\frac{1}{8}+\frac{1}{7}=\frac{7+8}{56}=\frac{15}{56}\).
\(\frac{8}{6}-\frac{2}{6}=\frac{6}{6}=1\).
\(\frac{8}{6}+\frac{7}{6}=\frac{15}{6}=2\frac{1}{2}\).
