Ответ:
а) \(4\frac{3}{13}=\frac{55}{13}\), \(1\frac{7}{26}=\frac{33}{26}\).
\(\frac{55}{13}\cdot\frac{33}{26}=\frac{165}{26}=6\frac{9}{26}\).
б) \(4\frac{2}{7}=\frac{30}{7}\), \(3\frac{3}{14}=\frac{45}{14}\).
\(\frac{30}{7}:\frac{45}{14}=\frac{30}{7}\cdot\frac{14}{45}=\frac{4}{3}=1\frac{1}{3}\).
в) \(\frac{3,2}{19,2}=\frac{32}{192}=\frac{1}{6}\).
г) \(1,35=\frac{27}{20}\), \(3\frac{3}{4}=\frac{15}{4}\).
\(\frac{27}{20}:\frac{15}{4}=\frac{27}{20}\cdot\frac{4}{15}=\frac{9}{25}=0,36\).
Ответ: а) \(6\frac{9}{26}\); б) \(1\frac{1}{3}\); в) \(\frac{1}{6}\); г) \(0,36\).
