3. Выполните деление: а) 4 3/8 : 5 1/4; б) 5 7/13 : 4/39; в) 45 10/29 : 5; г) 1 7/25 : 2 6/25; д) 3 5/9 : 4; е) 0 : (4/5 : 4/5); ж) 3 3/11 : 27/44; з) 1 7/9 : 3 3/7.

а) \(4\frac{3}{8}:5\frac{1}{4}=\frac{35}{8}:\frac{21}{4}=\frac{35}{8}\cdot\frac{4}{21}=\frac{5}{6}\).

б) \(5\frac{7}{13}:\frac{4}{39}=\frac{72}{13}\cdot\frac{39}{4}=54\).

в) \(45\frac{10}{29}:5=\frac{1315}{29}:5=\frac{263}{29}=9\frac{2}{29}\).

г) \(1\frac{7}{25}:2\frac{6}{25}=\frac{32}{25}:\frac{56}{25}=\frac{4}{7}\).

д) \(3\frac{5}{9}:4=\frac{32}{9}:4=\frac{8}{9}\).

е) \(0:\left(\frac{4}{5}:\frac{4}{5}\right)=0:1=0\).

ж) \(3\frac{3}{11}:\frac{27}{44}=\frac{36}{11}\cdot\frac{44}{27}=\frac{16}{3}=5\frac{1}{3}\).

з) \(1\frac{7}{9}:3\frac{3}{7}=\frac{16}{9}:\frac{24}{7}=\frac{16}{9}\cdot\frac{7}{24}=\frac{14}{27}\).

Ответ: а) \(\frac{5}{6}\); б) 54; в) \(9\frac{2}{29}\); г) \(\frac{4}{7}\); д) \(\frac{8}{9}\); е) 0; ж) \(5\frac{1}{3}\); з) \(\frac{14}{27}\).
