a) $$9\frac{1}{4} = \frac{9 \cdot 4 + 1}{4} = \frac{36 + 1}{4} = \frac{37}{4}$$
б) $$5\frac{6}{7} = \frac{5 \cdot 7 + 6}{7} = \frac{35 + 6}{7} = \frac{41}{7}$$
в) $$2\frac{3}{10} = \frac{2 \cdot 10 + 3}{10} = \frac{20 + 3}{10} = \frac{23}{10}$$
г) $$8\frac{12}{17} = \frac{8 \cdot 17 + 12}{17} = \frac{136 + 12}{17} = \frac{148}{17}$$
д) $$11\frac{5}{6} = \frac{11 \cdot 6 + 5}{6} = \frac{66 + 5}{6} = \frac{71}{6}$$
e) $$5\frac{6}{13} = \frac{5 \cdot 13 + 6}{13} = \frac{65 + 6}{13} = \frac{71}{13}$$
