Solution

The correct option is D $16 + 5 - 10 \times 4 \div 3 = 9$
$16 \times 5 \div 10 + 4 - 3 = 16 \times \frac{1}{2} + 1$
$= 8 + 1 = 9$ (true)

Use the distributivity of multiplication of rational numbers over their addition to simplify:

(i) $\frac{3}{5} \times (\frac{35}{24} + \frac{10}{1})$

(ii) $\frac{- 5}{4} \times (\frac{8}{5} + \frac{16}{5})$

(iii) $\frac{2}{7} \times (\frac{7}{16} - \frac{21}{4})$

(iv) $\frac{3}{4} \times (\frac{8}{9} - 40)$
