- $$9\frac{2}{7} = \frac{9 \cdot 7 + 2}{7} = \frac{63 + 2}{7} = \frac{65}{7}$$
- $$4\frac{5}{42} = \frac{4 \cdot 42 + 5}{42} = \frac{168 + 5}{42} = \frac{173}{42}$$
- $$2\frac{9}{96} = \frac{2 \cdot 96 + 9}{96} = \frac{192 + 9}{96} = \frac{201}{96} = \frac{67}{32}$$
Ответ: \(\frac{65}{7}\); \(\frac{173}{42}\); \(\frac{67}{32}\).
