Chapter 12, Problem 9QC

To determine

To find: the product of the expression.

Answer to Problem 9QC

The product of the expression is $\frac{7}{256}$ .

Explanation of Solution

Given information:

The expression is $\frac{4}{32}·\frac{7}{32}$ .

Calculation: to find the product of the expression, first multiply the numerator and denominator and then simplify,

  $\begin{array}{l}\frac{4}{32}·\frac{7}{32}=\frac{4·7}{32·32}\text{ [multiply the numerator and denominator]}\\ \frac{4}{32}·\frac{7}{32}=\frac{28}{1024}\text{ [multiply]}\\ \frac{4}{32}·\frac{7}{32}=\frac{7}{256}\text{ [simplify]}\end{array}$

Thus, the product is $\frac{7}{256}$ .
