Question
Evaluate: $3 \frac{1}{8} \times\left(-2 \frac{2}{5}\right)$
✓
Answer
$\begin{aligned} & 3 \frac{1}{8} \times\left(-2 \frac{2}{5}\right) \\ & =\frac{3 \times 8+1}{8} \times\left(-\frac{2 \times 5+2}{5}\right) \\ & =\frac{25}{8} \times\left(-\frac{12}{5}\right)=\frac{25 \times(-12)}{8 \times 5} \\ & =\frac{5 \times(-3)}{2 \times 1}=\frac{-15}{2}\end{aligned}$
