a)\(\frac{35}{12}+\frac{12}{11}=\frac{385}{132}+\frac{144}{132}=\frac{529}{132}\)

\(\frac{8}{9} +\frac{2}{3}=\frac{8}{9}+\frac{6}{9}=\frac{14}{9}\)

\(\frac{7}{8}+\frac{1}{6}=\frac{21}{24}+\frac{4}{24}=\frac{25}{24}\)

b)\(3+\frac{5}{6}=\frac{18}{6}+\frac{5}{6}=\frac{23}{6}\)

\(\frac{11}{3}+2=\frac{11}{3}+\frac{6}{3}=\frac{17}{3}\)

\(\frac{1}{2}+\frac{5}{6}=\frac{3}{6}+\frac{5}{6}=\frac{8}{6}=\frac{4}{3}\)

\(\frac{6}{4}+\frac{3}{5}=\frac{30}{20}+\frac{12}{20}=\frac{42}{20}=\frac{21}{10}\)

\(\frac{23}{7}+\frac{2}{6}=\frac{23}{7}+\frac{1}{3}=\frac{69}{21}+\frac{7}{21}=\frac{76}{21}\)
