Answer 1

$5 \times \frac{3}{4} = \frac{23}{4}$
$3 \times \frac{1}{4} = \frac{13}{4}$
$\frac{23}{4} - \frac{13}{4} = \frac{10}{4} = \frac{5}{2}$

$18 \times \frac{3}{12} = \frac{219}{12} = \frac{73}{4}$
$12 \times \frac{1}{8} = \frac{97}{8}$
$\frac{73}{4} - \frac{97}{8} = \frac{194}{8} - \frac{97}{8} = \frac{97}{8}$
