Chapter 6.5, Problem 20PPS

To determine

To Solve: The equation $\frac{10.2}{4}=\frac{h}{12}$

Answer to Problem 20PPS

  $h=31.2$

Explanation of Solution

Given information:

The equation $\frac{10.2}{4}=\frac{h}{12}$

Concept and Formula Used:

To solve the equation bring variable to one side and constant to other side and use cross multiplication.

Calculation:

The given equation is $\frac{10.2}{4}=\frac{h}{12}$

Cross multiply

  $\begin{array}{l}\frac{10.2}{4}=\frac{h}{12}\\ 10.4\times 12=h\times 4\\ 124.8=4h\\ \text{Divide both side by 4}\\ \frac{124.8}{4}=\frac{4h}{4}\\ 31.2=1h\\ \text{or }h=31.2\end{array}$

Conclusion:

  $h=31.2$
