Question

In a college of exactly 2860 students , exactly 70% are male. What is the number of female students

Answer 1

You are given the number of college students which is 2860. You are also given the male percentage in that college which is 70%. You are asked to find the number of female students. This is a percentage problem. You need to multiply 70% or 0.70 to 2860 and you get the number of male students. Then subtract this value to the total number of students and you will get the number of female students.  

Number of male students = 0.7 * 2860 = 2002
Number of female students = 2860 – 2002 = 858

Answer 2

If we know that 70% are male, 30% must be female...

30% as a decimal is 0.3

0.3 x 2860 = 858

So, there are 858 female students:)
