Calculation to show 15/20 as a percentage

Method #1

First, you need to adjust the value of the given denominator such that we need to make them 100. In this case, we are provided with the fraction as 15/20. So to change the denominator 20 of the given fraction to a hundred we need to divide 100 by 20.


100÷20 = 5

    \[ \frac{100}{20}=5 \]

Now with the multiple 5, you need to multiply both the numerator and the denominator by 5 to yield the results.


(15×5)÷(20×5) = 75/100

    \[ \frac{(15\times5)}{(20\times5)}=\frac{75}{100} \]

Hence the required percentage to the given fraction 15/20 is 75%

To do so you have to divide the numerator by the denominator where the numerator 15 becomes the dividend and the denominator 20 is the divisor.

15÷20 = 0.75

Now you need to multiply the obtained decimal value by 100 to get your required percentage.


0.75×100 = 75%


Both the steps that are used to convert the fraction 15/20 to percentage are easy and if you keep practicing then you will easily be able to yield the answer to your question.
