120/320 = 37.5%
A value like 120/320, or 37.5%, can show up in everyday situations such as a test score, a store discount, or the amount of a project that is finished. For example, if you complete 120 pages of a 320-page book, you have read a little more than one-third of it.
To picture 37.5% quickly, think of it as three-eighths, which is just less than half. On a group of 320 objects, it would look like a bit more than 100 objects but clearly fewer than half.
A common mistake is to treat 37.5% as if it were close to 75% because both numbers include “.5.” The decimal part does not determine the whole percentage by itself, so 37.5% is less than half, while 75% is three-quarters.
