18/72 = 25%
A value like 18/72, or 25%, can show up in everyday life when one-fourth of something is involved. For example, it could describe 18 students out of a class of 72, a 25% discount on a purchase, or one-quarter of a battery’s charge being used.
You can picture 25% quickly as one out of every four equal parts. Imagine a pizza cut into four equal slices: 18/72 represents the same share as one slice out of the whole pizza.
A common mistake is thinking 18/72 is close to 50% because both numbers are fairly large. The actual size of the fraction depends on how the numerator compares with the denominator, and 18 is only one-fourth of 72.
