If a class of 30 chemistry students have 17 of the students who are female. What percentage of students is female?
17 out of 30 is 17/30. Divide the numerator by the denominator to get the percent. 17 divided by 30 is .5666. You should probably round to .57 which is 57%.
Since 17 is a definite number and 30 is a definite number, there are no "significant figures" to worry about; therefore, you may retain the decimals and round to 56.67%
