High School Placement Test (HSPT) Practice Test

To determine the simplest form of 72% expressed as a fraction, we start by understanding what percentage means. The term "percentage" indicates a fraction out of 100. Therefore, 72% can be initially expressed as 72/100.

Next, we simplify the fraction 72/100. This involves finding the greatest common divisor (GCD) of the numerator (72) and denominator (100). The GCD of 72 and 100 is 4. To simplify the fraction, we divide both the numerator and the denominator by 4.

When dividing, we have:

- 72 ÷ 4 = 18

- 100 ÷ 4 = 25

Thus, the fraction in its simplest form is 18/25. This means that 72%, when expressed as a fraction in its simplest form, is 18/25.

The other choices, while valid fractions, do not represent the simplest form of 72%. For example, 36/50 can be simplified further to 18/25 as well, indicating it's not in its simplest form. Similarly, 72/100 is actually the initial fraction before simplification, and 9/12 does not correctly represent 72% in
