To determine

To evaluate: the given expression

Answer to Problem 13STP

The required solution is 0.1.

Explanation of Solution

Given:

  $abc$

  $a=-\frac{2}{5},b=\frac{20}{32},$ and $c=-\frac{4}{10}.$

Calculation:

Given: $abc$

Substitute the values of $a=-\frac{2}{5},b=\frac{20}{32}$ and $c=-\frac{4}{10}$

  $\begin{array}{l}abc=-\frac{2}{5}\times \frac{20}{32}\times -\frac{4}{10}\\ =\frac{1}{10}\\ =0.1\end{array}$

Conclusion:

Hence, the required solution is 0.1.
