a) \(5 \cdot 2\frac{3}{5} = 5 \cdot \frac{13}{5} = \frac{5 \cdot 13}{5} = 13\)
б) \(4\frac{3}{8} \cdot 16 = \frac{35}{8} \cdot 16 = \frac{35 \cdot 16}{8} = 35 \cdot 2 = 70\)
в) \(1\frac{2}{9} \cdot 9 = \frac{11}{9} \cdot 9 = \frac{11 \cdot 9}{9} = 11\)
г) \(1 \cdot 7\frac{8}{11} = 1 \cdot \frac{85}{11} = \frac{85}{11} = 7\frac{8}{11}\)
д) \(2\frac{2}{13} \cdot 0 = 0\)
e) \(0 \cdot 1\frac{6}{17} = 0\)
Ответ: a) 13; б) 70; в) 11; г) \(7\frac{8}{11}\); д) 0; e) 0
