What percentage of a class of 40 students are female if 14 are male?

To determine the percentage of female students in a class of 40, given that there are 14 male students, first calculate how many students are female.

The total number of students in the class is 40, and if 14 of them are male, the number of female students can be found by subtracting the number of male students from the total:

40 (total students) - 14 (male students) = 26 (female students).

Next, to find the percentage of female students, you take the number of female students and divide it by the total number of students, then multiply that result by 100:

(26 female students / 40 total students) * 100 = 65%.

This calculation shows that 65% of the students in the class are female. Therefore, the first choice is the correct answer, as it accurately represents the proportion of female students in this scenario.
