Ratio is comparison between two numbers. Fraction is part of whole. Ratio can be expressed in the form of fraction. Ratio can be converted into fractional form with the help of this calculator.
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
          
          $\frac{20}{30}$ = $\frac{20\div 10}{30\div 10}$ = $\frac{2}{3}$
