\frac{36}{54} = \frac{8}{n}

$\frac{36}{54} = \frac{8}{n}$

Step 1

Rewrite the equation as

\frac{8}{n} = \frac{36}{54}

$\frac{8}{n} = \frac{36}{54}$ .

\frac{8}{n} = \frac{36}{54}

$\frac{8}{n} = \frac{36}{54}$

Step 2.2.1

Factor

18

$18$ out of

54

$54$ .

\frac{8}{n} = \frac{18 \cdot 2}{18 \cdot 3}

$\frac{8}{n} = \frac{18 \cdot 2}{18 \cdot 3}$

Step 2.2.2

Cancel the common factor.

$\frac{8}{n} = \frac{18 \cdot 2}{18 \cdot 3}$

Step 2.2.3

Rewrite the expression.

$\frac{8}{n} = \frac{2}{3}$

Step 3

Multiply the numerator of the first fraction by the denominator of the second fraction. Set this equal to the product of the denominator of the first fraction and the numerator of the second fraction.

$8 \cdot 3 = n \cdot 2$
