Ответ:
- \(\dfrac12-\dfrac14=\dfrac24-\dfrac14=\dfrac14\).
- \(\dfrac59-\dfrac13=\dfrac59-\dfrac39=\dfrac29\).
- \(\dfrac7{10}-\dfrac35=\dfrac7{10}-\dfrac6{10}=\dfrac1{10}\).
- \(\dfrac{16}{27}-\dfrac19=\dfrac{16}{27}-\dfrac3{27}=\dfrac{13}{27}\).
- \(\dfrac35-\dfrac{13}{45}=\dfrac{27}{45}-\dfrac{13}{45}=\dfrac{14}{45}\).
- \(\dfrac13-\dfrac8{27}=\dfrac9{27}-\dfrac8{27}=\dfrac1{27}\).
- \(\dfrac12-\dfrac13=\dfrac36-\dfrac26=\dfrac16\).
- \(\dfrac35-\dfrac13=\dfrac9{15}-\dfrac5{15}=\dfrac4{15}\).
- \(\dfrac78-\dfrac23=\dfrac{21}{24}-\dfrac{16}{24}=\dfrac5{24}\).
- \(\dfrac34-\dfrac47=\dfrac{21}{28}-\dfrac{16}{28}=\dfrac5{28}\).
- \(\dfrac9{16}-\dfrac{11}{24}=\dfrac{27}{48}-\dfrac{22}{48}=\dfrac5{48}\).
- \(\dfrac{11}{12}-\dfrac{11}{18}=\dfrac{33}{36}-\dfrac{22}{36}=\dfrac{11}{36}\).
