Solve for n 15 is 30% of what number

$15$ is $30 %$ of what number

Step 1

Write the problem as a mathematical expression.

$15 = 30 % \cdot n$

Step 2

Rewrite the equation as $30 % \cdot n = 15$ .

$30 % \cdot n = 15$

Step 3

Divide each term in $(30 % \cdot n) = 15$ by $30 %$ and simplify.

Divide each term in $(30 % \cdot n) = 15$ by $30 %$ .

$\frac{(30 % \cdot n)}{30 %} = \frac{15}{30 %}$

Simplify the left side.

Cancel the common factor of $30 %$ .

Cancel the common factor.

$\frac{30 % \cdot n}{30 %} = \frac{15}{30 %}$

Divide $n$ by $1$ .

$n = \frac{15}{30 %}$

Simplify the right side.

Convert $30 %$ to a decimal.

$n = \frac{15}{0.3}$

Divide $15$ by $0.3$ .

$n = 50$
