\(\frac{1}{2}+\frac{31}{20}=\frac{10}{20}+\frac{31}{20}=\frac{41}{20}=2\frac{1}{20}\).
\(\frac{1}{2}+\frac{33}{50}=\frac{25}{50}+\frac{33}{50}=\frac{58}{50}=\frac{29}{25}=1\frac{4}{25}\).
\(\frac{1}{4}+\frac{31}{20}=\frac{5}{20}+\frac{31}{20}=\frac{36}{20}=\frac{9}{5}=1\frac{4}{5}\).
\(\frac{1}{5}+\frac{17}{10}=\frac{2}{10}+\frac{17}{10}=\frac{19}{10}=1\frac{9}{10}\).
\(\frac{1}{5}+\frac{19}{20}=\frac{4}{20}+\frac{19}{20}=\frac{23}{20}=1\frac{3}{20}\).
\(\frac{1}{5}+\frac{41}{50}=\frac{10}{50}+\frac{41}{50}=\frac{51}{50}=1\frac{1}{50}\).
\(\frac{1}{5}+\frac{27}{20}=\frac{4}{20}+\frac{27}{20}=\frac{31}{20}=1\frac{11}{20}\).
\(\frac{1}{10}+\frac{29}{50}=\frac{5}{50}+\frac{29}{50}=\frac{34}{50}=\frac{17}{25}\).
\(\frac{1}{10}+\frac{43}{50}=\frac{5}{50}+\frac{43}{50}=\frac{48}{50}=\frac{24}{25}\).
\(\frac{1}{2}+\frac{11}{10}=\frac{5}{10}+\frac{11}{10}=\frac{16}{10}=\frac{8}{5}=1\frac{3}{5}\).
\(\frac{11}{20}+\frac{3}{10}=\frac{11}{20}+\frac{6}{20}=\frac{17}{20}\).
\(\frac{47}{60}+\frac{14}{30}=\frac{47}{60}+\frac{28}{60}=\frac{75}{60}=\frac{5}{4}=1\frac{1}{4}\).
\(\frac{1}{4}+\frac{17}{20}=\frac{5}{20}+\frac{17}{20}=\frac{22}{20}=\frac{11}{10}=1\frac{1}{10}\).
\(\frac{71}{120}+\frac{35}{12}=\frac{71}{120}+\frac{350}{120}=\frac{421}{120}=3\frac{61}{120}\).
\(\frac{27}{85}+\frac{15}{17}=\frac{27}{85}+\frac{75}{85}=\frac{102}{85}=1\frac{17}{85}\).
