Given that 2500 students entered the Teacher Education Program.
[tex]\text{Number of male students + Number of female students = 2500}[/tex]
20% of the students are male. Thus,
[tex]\begin{gathered} \text{Number of male students = 20\% of 2500} \\ \Rightarrow\frac{20}{100}\times2500 \\ \text{Number of male students = 500} \end{gathered}[/tex]
Thus,
[tex]\begin{gathered} \text{Number of male students + Number of female students = 2500} \\ 500\text{ + Number of female students =2500} \\ \Rightarrow Number\text{ of female students = 2500 -500 = 2000 } \end{gathered}[/tex]
Thus, the ratio of the number of males to the number of females is evaluated as
[tex]\begin{gathered} \text{Number of female : Number of male} \\ 2000\text{ : 500} \\ reducing\text{ to the lowest term gives} \\ 4\colon1 \end{gathered}[/tex]
Hence, the ratio of the number of females to the number of males is thus 4:1
