To convert 80 percent into a fraction, start by remembering that percent means ‘per hundred.’ Therefore, 80 percent can be written as:
80% = 80/100
Next, we simplify the fraction. Both the numerator (80) and the denominator (100) can be divided by their greatest common divisor, which is 20:
80 ÷ 20 = 4
100 ÷ 20 = 5
This gives us:
80/100 = 4/5
So, 80 percent as a fraction is 4/5.
