Hint:
This is a problem in which the student has to bring the percentage into a fraction in its simplest form. This can be treated as a problem in fraction in which the first step would be to convert percentage into a fraction by dividing it by 100 . And then the student can bring both the numbers in its simplest form.

Complete step by step solution:
Recall that "percent" means "per hundred".
Therefore, we can write that 20
Next, try to reduce the fraction.
Since the greatest common divisor of the numerator and the denominator equals 20, we can write that
Therefore, 20÷20100÷20=15 .

Hence, 20%=15.

Note:
Only important step in this sum is to first bring the percentage into a fraction and then in terms of its prime factors. Sometimes when the complicated sum like 20 , it is advisable that the student first converts all the terms into the form of a fraction and then cancels out common terms after which, he/she should reduce the remaining terms to its prime factors.
