What is the simplest fractional form of 20%?

To convert a percentage into its simplest fractional form, it's important to remember that a percentage represents a part out of 100. Therefore, 20% can be expressed as a fraction with 20 as the numerator and 100 as the denominator, resulting in the fraction 20/100.

To simplify this fraction, both the numerator and the denominator need to be divided by their greatest common divisor (GCD). In this case, the GCD of 20 and 100 is 20. When you divide both the numerator and the denominator by 20, you get:

20 ÷ 20 = 1
100 ÷ 20 = 5

Thus, 20% simplifies to the fraction 1/5. This fraction is already in its simplest form because the numerator (1) cannot be simplified further, and there are no common factors between the numerator and the denominator other than 1.

This process illustrates why the correct answer is 1/5, as it accurately reflects the simplification of 20% into a fractional representation.
