Answer 1

$3 \frac{3}{4} = \frac{3 \times 4 + 3}{4} = \frac{15}{4} \\ 5 \frac{7}{10} = \frac{5 \times 10 + 7}{10} = \frac{57}{10} \\ 14 \frac{4}{5} = \frac{14 \times 5 + 4}{5} = \frac{74}{5} \\ 8 \frac{7}{12} = \frac{8 \times 12 + 7}{12} = \frac{103}{12} \\ 24 \frac{3}{4} = \frac{24 \times 4 + 3}{4} = \frac{99}{4} \\ 15 \frac{3}{7} = \frac{15 \times 7 + 3}{7} = \frac{108}{7} \\ 9 \frac{9}{11} = \frac{9 \times 11 + 9}{11} = \frac{108}{11} \\ 14 \frac{20}{21} = \frac{14 \times 21 + 20 }{21} = \frac{314}{21} \\ 12 \frac{3}{23} = \frac{12 \times 23 + 3}{23} = \frac{279}{23} \\ 15 \frac{5}{24} = \frac{15 \times 24 + 5}{24} = \frac{365}{24}$
