The ratio of 17 and a number
as an expression

Hope this helps: When we have 17 parts out of 100 (or part to whole ratio 17 : 100), we have 17%. The symbol % is called the percent sign. The expression 17% means 17 parts out of 100. Therefore, 17% is equivalent to the common fraction and to the decimal fraction 0.17.

Sorry if it’s wrong
