a) $$9\frac{1}{4} = \frac{9 \cdot 4 + 1}{4} = \frac{36 + 1}{4} = \frac{37}{4}$$
Ответ: $$\frac{37}{4}$$
б) $$5\frac{6}{10} = \frac{5 \cdot 10 + 6}{10} = \frac{50 + 6}{10} = \frac{56}{10}$$
Ответ: $$\frac{56}{10}$$
в) $$2\frac{3}{7} = \frac{2 \cdot 7 + 3}{7} = \frac{14 + 3}{7} = \frac{17}{7}$$
Ответ: $$\frac{17}{7}$$
г) $$8\frac{12}{17} = \frac{8 \cdot 17 + 12}{17} = \frac{136 + 12}{17} = \frac{148}{17}$$
Ответ: $$\frac{148}{17}$$
д) $$11\frac{5}{6} = \frac{11 \cdot 6 + 5}{6} = \frac{66 + 5}{6} = \frac{71}{6}$$
Ответ: $$\frac{71}{6}$$
