Solve for f A=1/3f*p

$A = \frac{1}{3} f \cdot p$

Rewrite the equation as $\frac{1}{3} f \cdot p = A$ .

$\frac{1}{3} f \cdot p = A$

Divide each term in $(\frac{1}{3} f \cdot p) = A$ by $\frac{1}{3} p$ and simplify.

Divide each term in $(\frac{1}{3} f \cdot p) = A$ by $\frac{1}{3} p$ .

$\frac{(\frac{1}{3} f \cdot p)}{\frac{1}{3} p} = \frac{A}{\frac{1}{3} p}$

Simplify the left side.

Cancel the common factor of $\frac{1}{3}$ .

Cancel the common factor.

$\frac{\frac{1}{3} f \cdot p}{\frac{1}{3} p} = \frac{A}{\frac{1}{3} p}$

Rewrite the expression.

$\frac{f \cdot p}{p} = \frac{A}{\frac{1}{3} p}$

Cancel the common factor of $p$ .

Cancel the common factor.

$\frac{f \cdot p}{p} = \frac{A}{\frac{1}{3} p}$

Divide $f$ by $1$ .

$f = \frac{A}{\frac{1}{3} p}$

Simplify the right side.

Combine $\frac{1}{3}$ and $p$ .

$f = \frac{A}{\frac{p}{3}}$

Multiply the numerator by the reciprocal of the denominator.

$f = A \frac{3}{p}$

Combine $A$ and $\frac{3}{p}$ .

$f = \frac{A \cdot 3}{p}$

Move $3$ to the left of $A$ .

$f = \frac{3 A}{p}$
