Ответ:
- \(\frac3{16}:5=\frac3{16}\cdot\frac15=\frac3{80}\);
- \(\frac17:4=\frac17\cdot\frac14=\frac1{28}\);
- \(1:\frac5{12}=1\cdot\frac{12}{5}=\frac{12}{5}=2\frac25\);
- \(7:\frac17=7\cdot7=49\);
- \(4:\frac98=4\cdot\frac89=\frac{32}{9}=3\frac59\).
Ответ: а) \(\frac3{80}\); б) \(\frac1{28}\); в) \(2\frac25\); г) 49; д) \(3\frac59\).
