Basic Math Examples

80 % \cdot n = 40

$80 % \cdot n = 40$

Step 1

Divide each term in

80 % \cdot n = 40

$80 % \cdot n = 40$ by

80 %

$80 %$ .

\frac{80 % \cdot n}{80 %} = \frac{40}{80 %}

$\frac{80 % \cdot n}{80 %} = \frac{40}{80 %}$

Step 2.1.1

Cancel the common factor.

\frac{80 % \cdot n}{80 %} = \frac{40}{80 %}

$\frac{80 % \cdot n}{80 %} = \frac{40}{80 %}$

Step 2.1.2

Divide

n

$n$ by

1

$1$ .

n = \frac{40}{80 %}

$n = \frac{40}{80 %}$

n = \frac{40}{80 %}

$n = \frac{40}{80 %}$

n = \frac{40}{80 %}

$n = \frac{40}{80 %}$

Step 3.1

Convert

80 %

$80 %$ to a decimal.

n = \frac{40}{0.8}

$n = \frac{40}{0.8}$

Step 3.2

Divide

40

$40$ by

0.8

$0.8$ .

n = 50

$n = 50$

n = 50

$n = 50$
