Answer 2

4)

$4 \frac{5}{12} - 1 \frac{1}{2} + \div (2 \frac{1}{6} + \frac{8}{15} ) \times 1 \frac{4}{5}$

$\frac{53}{12} - \frac{3}{2} \div ( \frac{13}{6} + \frac{8}{15} ) \times \frac{4}{5}$

$\frac{53}{12} - \frac{3}{2} + \frac{81}{30} \times \frac{4}{5}$

$\frac{53}{12} - \frac{3}{2} \div \frac{27}{10} \times \frac{4}{5}$

$\frac{53}{12} - \frac{3}{2} \times \frac{10}{27} \times \frac{4}{5}$

$\frac{53}{12} - \frac{4}{9}$

$\frac{143}{36} = 3 \frac{35}{36}$
