Answer 1

$3 \frac{1}{2} = \frac{2 \times 3 + 1}{2} = \frac{7}{2}$

$2 \frac{3}{7} = \frac{2 \times 7 + 3}{7} = \frac{17}{7}$

$2 \frac{3}{8} = \frac{8 \times 2 + 3}{8 } = \frac{19}{8}$

$5 \frac{3}{8} = \frac{8 \times 5 + 3}{8} = \frac{43}{8}$

$6 \frac{5}{12} = \frac{12 \times 6 + 5}{12} = \frac{77}{12}$

$4 \frac{2}{17} = \frac{17 \times 4 + 2}{17} = \frac{70}{17}$

$5 \frac{3}{16} = \frac{5 \times 16 + 3}{16} = \frac{83}{16}$

$7 \frac{7}{18} = \frac{18 \times 7 + 7 = }{18} = \frac{133}{18}$

$3 \frac{7}{25} = \frac{3 \times 25 + 7}{25} = \frac{82}{25}$

$6 \frac{9}{16} = \frac{16 \times 6 + 9}{16} = \frac{105}{16}$

$4 \frac{17}{18} = \frac{18 \times 4 + 17}{18} = \frac{89}{18}$

$5 \frac{7}{15} = \frac{5 \times 15 + 7}{15} = \frac{82}{15}$
