Ответ:
- \(7\cdot\frac4{37}=\frac{28}{37}.\)
- \(\frac7{15}\cdot3=\frac75=1\frac25.\)
- \(\frac8{13}\cdot26=16.\)
- \(4\frac47\cdot2\frac{11}{12}=\frac{32}{7}\cdot\frac{35}{12}=\frac{40}{3}=13\frac13.\)
- \(1\frac2{13}\cdot1\frac58=\frac{15}{13}\cdot\frac{13}{8}=1\frac78.\)
- \(1\frac2{13}\cdot1\frac58\cdot1\frac17=\frac{15}{8}\cdot\frac87=2\frac17.\)
