Answer 2

$5 \frac{2}{3}$

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

$= \frac{15 + 2}{3}$

$= \frac{17}{3}$

$4 - \frac{3}{2}$

$= \frac{4}{1} - \frac{3}{2}$

$= \frac{4 \times 2}{1 \times 2} - \frac{3}{2}$

$= \frac{8}{2} - \frac{3}{2}$

$= \frac{8 - 3}{2}$

$= \frac{5}{2}$

$= 2 \frac{1}{2} \: \: \: or \: \: \: 2,5$
