What is the fraction equivalent of 15% in lowest terms?

To determine the fraction equivalent of 15% in lowest terms, it's important to understand the concept of percentages as a fraction of 100. The percentage 15% means 15 out of 100, which can be written as the fraction 15/100.

Next, this fraction can be simplified. To simplify 15/100, we find the greatest common divisor (GCD) of the numerator (15) and the denominator (100). The GCD of 15 and 100 is 5.

Now, we can divide both the numerator and the denominator by the GCD:

• 15 ÷ 5 = 3

• 100 ÷ 5 = 20

This gives us the fraction 3/20.

3/20 is indeed in its lowest terms, as there are no common factors between the numerator and the denominator other than 1. Therefore, the fraction equivalent of 15% is 3/20.

This is why the correct answer is B.
