Answer 2

$\frac{9}{16} \times ( \frac{1}{4} + \frac{5}{12} ) - \frac{8}{15} \div \frac{16}{45}$

$\frac{1}{4} + \frac{5}{12} = \frac{3}{12} + \frac{5}{12} = \frac{8}{12} = \frac{2}{3}$

$\frac{9}{16} \times \frac{2}{3} = \frac{18}{42} = \frac{3}{7}$

$\frac{8}{15} \div \frac{16}{45} = \frac{8}{15} \times \frac{45}{16} = \frac{1}{1} \times \frac{3}{2} = \frac{3}{2}$

$\frac{3}{7} - \frac{3}{2} = \frac{6}{14} - \frac{21}{14} = \frac{ - 15}{14}$

$\frac{ - 15}{14} = - 1 \times \frac{ - 1}{14}$
