Answer 2

Salut,

$3 \frac{1}{2} = \frac{3 \times 2 + 1}{2} = \frac{6 + 1}{2} = \frac{7}{2}$

$5 \frac{2}{3 } = \frac{5 \times 3 + 2}{3} = \frac{15 + 2}{3} = \frac{17}{3}$

$7 \frac{5}{2} = \frac{7 \times 2 + 5}{2} = \frac{14 + 5}{2} = \frac{19}{2}$

$8 \frac{2}{5} = \frac{8 \times 5 + 2}{5} = \frac{40 + 2}{5} = \frac{42}{5}$

$12 \frac{3}{4} = \frac{12 \times 4 + 3}{4} = \frac{48 + 3}{4} = \frac{51}{4}$

$11 \frac{3}{2} = \frac{11 \times 2 + 3}{2} = \frac{22 + 3}{2} = \frac{25}{2 }$
