Answer 2

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

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

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

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

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

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