Question

Simplify: $(1\frac{1}{3}+\frac{2}{3})\times \frac{8}{15}$

Answer 1

$(1\frac{1}{3}+\frac{2}{3})\times \frac{8}{15}=(\frac{4}{3}+\frac{2}{3})\times \frac{8}{15}$
$=\left(\frac{6}{3}\right)\times \frac{8}{15}$ [bracket is given preference]
$=2\times \frac{8}{15}=\frac{16}{15}=1\frac{1}{15}$.
