Answer 1

$a) \frac{a}{3} = \frac{5}{b} \\ a \times b = 3 \times 5 = 15 \\ 30 - \frac{150}{a \times b} = \\ 30 - \frac{150}{15} = \\ 30 - 10 = 20$

$b)\frac{a}{4} = \frac{8}{b} \\ a \times b = 4 \times 8 = 24 \\ \frac{2}{c} = \frac{d}{16} \\ c \times d = 2 \times 16 = 32 \\ a \times b - c \times d = \\ 24 - 32 = - 8$
