18/72 = 25%
The fraction 18/72 represents 25%, or one-fourth of a whole. You might see a value like this when 18 out of 72 students choose the same lunch option, or when a store marks an item down by one-quarter.
To picture 25% quickly, imagine a square split into four equal parts with one part shaded. It is also about the same as one out of every four objects, which makes it easy to estimate in a group.
A common mistake is thinking that 25% means 25 whole items instead of 25 out of every 100. The actual number depends on the total, so 25% of 72 is 18, while 25% of a different total would produce a different number.
