\(\frac34+\frac47=\frac{21+16}{28}=\frac{37}{28}=1\frac9{28}\)
\(\frac{13}{24}-\frac38=\frac{13-9}{24}=\frac{4}{24}=\frac16\)
\(\frac{11}{12}-\frac5{18}=\frac{33-10}{36}=\frac{23}{36}\)
\(\frac{13}{36}+\frac7{24}=\frac{26+21}{72}=\frac{47}{72}\)
\(\frac8{15}-\frac49=\frac{24-20}{45}=\frac4{45}\)
\(\frac56-\frac23+\frac29=\frac{15-12+4}{18}=\frac7{18}\)
