72/390 = ≈18.46%
Rounded to 2 decimal places.
A value like 72/390, or about 18.46%, can show up in everyday situations such as survey results, test scores, or the number of items sold from a larger supply. For example, if 72 out of 390 students choose the same activity, that choice represents a little less than one-fifth of the group.
To picture 18.46% quickly, think of a group divided into five roughly equal parts. One-fifth is 20%, so this fraction is just slightly smaller than one of those five parts.
A common mistake is to treat 18.46% as 18.46 rather than as a part of 100. It also helps to remember that 72/390 is already in a reasonable form for comparison, even though it can be simplified to 12/65.
