To convert 18 percent to a fraction, we start by recognizing that percent means ‘per hundred.’ So, 18 percent can be written as:
18% = 18/100
Next, we simplify the fraction. Both the numerator (18) and the denominator (100) can be divided by their greatest common divisor, which is 2:
18 ÷ 2 = 9
100 ÷ 2 = 50
This gives us:
18/100 = 9/50
Therefore, 18 percent as a fraction is 9/50.
