Answer 2

$\frac{7}{5} - \frac{2}{8} = \frac{8 \times 7 - 5 \times 2}{5 \times 8} = \frac{46}{40}$

$\frac{1}{4} + \frac{2}{9} = \frac{9 \times 1 + 4 \times 2}{4 \times 9} = \frac{17}{36}$

$\frac{46}{40} \times \frac{17}{36} = \frac{782}{1440}$

$\frac{782 \div 2}{1440 \div 2} = \frac{391}{720}$

$\frac{391}{720}$
