Ответ:
- \(\frac{8}{27}:\frac49=\frac{8}{27}\cdot\frac94=\frac23\).
- \(\frac{36}{47}:18=\frac{36}{47}\cdot\frac1{18}=\frac2{47}\).
- \(\frac{42}{48}:\frac67=\frac78\cdot\frac76=\frac{49}{48}\).
- \(3\frac19:\,2\frac{11}{12}=\frac{28}{9}:\frac{35}{12}=\frac{28}{9}\cdot\frac{12}{35}=\frac{16}{15}=1\frac1{15}\).
- \(\frac8{25}:3\frac15:1\frac14=\frac8{25}:\frac{16}{5}:\frac54=\frac8{25}\cdot\frac5{16}\cdot\frac45=\frac2{25}\).
- \(2{,}04:\frac35=\frac{51}{25}\cdot\frac53=\frac{17}{5}=3{,}4\).
