## Converting Ratios to Fractions

Ratios are converted into fractions by the following steps:Step 1: Find the factors of both the numerator and denominator.

Step 2: Find the Highest common factor of both the numerator and denominator.

Step 3: Divide both numerator and denominator by the highest common factor.

Here are some examples of converting ratio to fraction.

### Solved Examples

Question 1: Convert the ratio 12 : 15 into fraction.
Solution:
Given, $12 : 15$ = $\frac{12}{15}$

Factors of 12 = 1, 2, 3, 4, 6, 12

Factors of 15 = 1, 3, 5, 15

Highest common factor = 3

$\frac{12}{15}$ = $\frac{12\div 3}{15\div 3}$ = $\frac{4}{5}$

Question 2: Convert the ratio 20 : 30 into fraction.
Solution:
Given, $20 : 30$ = $\frac{20}{30}$

Factors of 20 = 1, 2, 4, 5, 10, 20

Factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30

Highest common factor = 10

$\frac{20}{30}$ = $\frac{20\div 10}{30\div 10}$ = $\frac{2}{3}$
