100%

Percent is based on the number 100.

Since a number percent is just that number divided by 100, to convert a single number into a percent, multiply by 100. Thus 3.45 = 345% = 345/100.

15 percent of 100 is 15. There is a total of 100% in any number. 1% of 100 is 1. 2% of 100 is 2. 3% of 100 is 3 and so on.
