​

Answer 1

Step-by-step explanation:

=15/4÷3/7of[45/24-9/6]of2/5

=15/4÷3/7 of 36/24 of 2/5

=15/4÷3/7×36/24 ×2/5

=15/4÷9/35

=175/12

Answer 2

$\frac{15}{4} \div \frac{3}{7} \: of \: [ \frac{45}{24} - ( \frac{2}{3} + \frac{5}{6} )]\: of \: \frac{2}{5}$

$\frac{15}{4} \div \frac{3}{7} \times [ \frac{45}{24} - ( \frac{4 + 5}{6} )] \times \frac{2}{5}$

$\frac{15}{4} \div \frac{3}{7} \times [ \frac{45}{24} - \frac{9}{6}] \times \frac{2}{5}$

$\frac{15}{4} \div \frac{3}{7} \times [ \frac{45 - 36}{24} ] \times \frac{2}{5}$

$\frac{15}{7} \times \frac{7}{3} \times \frac{9}{24} \times \frac{2}{5}$

$\frac{7 \times 3}{4 \times 4}$

$\frac{21}{16}$
