Answer:
1200 female students.
Explanation:
If 3 out of every 5 students are female, then:
2 out of every 5 students are Male.
Let the total number of students= x
Therefore:
[tex]\frac{2}{5}\times x=800[/tex]We then solve for x.
[tex]\begin{gathered} 2x=800\times5 \\ x=\frac{4000}{2} \\ x=2000 \end{gathered}[/tex]Therefore, the number of female students is:
[tex]\begin{gathered} \text{Female}=2000-800 \\ =1200 \end{gathered}[/tex]There are 1200 female students.
