\(\frac{5}{8}+\frac{5}{6}+\frac{7}{12}=\frac{15+20+14}{24}=\frac{49}{24}=2\frac{1}{24}\)
\(\frac{1}{5}+\frac{3}{8}-\frac{2}{9}=\frac{72+135-80}{360}=\frac{127}{360}\)
\(\frac{1}{4}+\frac{2}{9}-\frac{5}{36}=\frac{9+8-5}{36}=\frac{12}{36}=\frac{1}{3}\)
\(\frac{3}{4}+\frac{4}{5}+\frac{1}{20}=\frac{15+16+1}{20}=\frac{32}{20}=\frac{8}{5}=1\frac{3}{5}\)
\(\frac{3}{4}+\frac{5}{12}-\frac{1}{9}=\frac{27+15-4}{36}=\frac{38}{36}=\frac{19}{18}=1\frac{1}{18}\)
\(\frac{4}{15}+\frac{2}{5}+\frac{7}{10}=\frac{8+12+21}{30}=\frac{41}{30}=1\frac{11}{30}\)
