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