a) $$5 \cdot 2\frac{8}{9} = 5 \cdot \frac{26}{9} = \frac{130}{9} = 14\frac{4}{9}$$
б) $$4\frac{3}{8} \cdot 16 = \frac{35}{8} \cdot 16 = 35 \cdot 2 = 70$$
в) $$1\frac{2}{9} \cdot 9 = \frac{11}{9} \cdot 9 = 11$$
г) $$1 \cdot 7\frac{8}{11} = \frac{11}{11} + \frac{85}{11} = \frac{96}{11} = 8\frac{8}{11}$$
д) $$2\frac{2}{13} \cdot 0 = 0$$
е) $$0 \cdot 1\frac{6}{17} = 0$$
