How do you express answer as a percent?

Answer 1

A percent means--per 100. Let's say we know there is a groulp of 35 students of which 7 are girls. Q. What is the percent of girls in the group? A. First we look at the number of girls divided by the total number of students. This will give us a decimal number. In this case, O.2 To get the percent of girls, we convert this decimal to percent or per 100 by both multiplying and dividing by 100. We can do this without changing the value of 0.2 since 100/100=1. We just change the units. (In this case though we just don't do the division.) So this turns out to be 20/100 eg 20 per 100 or 20 percent.
