Question

Solve the following equation for f .

Answer 1

f = 3U/2

Explanation:$U\text{ = }\frac{2}{3}f$

cross multiply:

$\begin{gathered} U\text{ = }\frac{2f}{3} \\ 3(U)\text{ = 2f} \end{gathered}$

Divide both sides by 2:

$\begin{gathered} \frac{3U\text{ }}{2}\text{= }\frac{\text{2f}}{2} \\ f\text{ = }\frac{3U\text{ }}{2} \end{gathered}$
