Accepted Answer

\(\frac{14}{33}-\frac{21}{55}=\frac{70-63}{165}=\frac7{165}\).
\(\frac{15}{16}+\frac3{16}=\frac{18}{16}=1\frac18\).
\(2\frac79+\frac89=2+\frac{15}{9}=3\frac23\).
\(\frac1{28}+\frac{16}{35}=\frac5{140}+\frac{64}{140}=\frac{69}{140}\).
\(1\frac5{36}+\frac3{20}=1+\frac{25+27}{180}=1\frac{13}{45}\).
\(3\frac5{23}+8\frac{18}{23}=11+\frac{23}{23}=12\).
\(17\frac4{21}-3\frac14=14+\frac4{21}-\frac14=14-\frac5{84}=13\frac{79}{84}\).
\(31\frac{29}{48}-13\frac7{48}=18+\frac{22}{48}=18\frac{11}{24}\).
\(5-\frac3{14}=4\frac{11}{14}\).
\(62\frac8{37}-22\frac{10}{37}=40-\frac2{37}=39\frac{35}{37}\).
\(8\frac7{24}-1\frac5{64}=7+\frac{56-15}{192}=7\frac{41}{192}\).
\(\frac4{15}+\frac{11}{15}=1\).
