The problem asks to fully simplify the fraction $\frac{80}{100}$.

1. Problem Description

The problem asks to fully simplify the fraction $\frac{80}{100}$.

2. Solution Steps

To simplify the fraction $\frac{80}{100}$, we need to find the greatest common divisor (GCD) of the numerator (80) and the denominator (100).

We can find the GCD by listing the factors of each number:

Factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

Factors of 100: 1, 2, 4, 5, 10, 20, 25, 50, 100

The greatest common divisor is

2

0. Now we divide both the numerator and the denominator by the GCD:

$\frac{80}{20} = 4$

$\frac{100}{20} = 5$

Therefore, the simplified fraction is $\frac{4}{5}$.

3. Final Answer

$\frac{4}{5}$
