Chapter 1.2, Problem 9CYU

To determine

To evaluate: the givenexpression.

Answer to Problem 9CYU

The required value is 12

Explanation of Solution

Given: $\frac{gh}{j}$

  $\begin{array}{l}g=6\\ h=10\\ j=5\end{array}$

Calculation:

Given the expression $\frac{gh}{j}$ , we first substitute $g=6,h=10$ and $j=5.$

  $\frac{gh}{j}=\frac{6\times 10}{5}=6\times 10÷5$

Since, we have two operations multiplication and division, so according to the rules for order of operation, we have to look at the expression to see which operation comes first from left to right.

Since multiplication comes first, we will multiply first and then divide.

  $\begin{array}{l}6\times 10÷5=60÷5\\ =12\end{array}$

Therefore we have that the numerical value of the given expression is 12.

Conclusion:

Thus, the required value is 12
