5.04

This is a part because we are asked to find what part of 56 is 9 percent of 56. In order to find a part, we take the percentage and divide it by 100 to turn it into a decimal. We multiply this decimal by the original number to get the answer. Thus, we divide 9 by 100 to get .09. We multiply 56 by .09 to get an answer of 5.04.
