1. There are 50 learners in the Basic 9 class of Japetimen Re Base School. Of this number, 20 of them are females.

i) Find the fraction of males in the class.

ii) Find the percentage of females in the class.

**Solution:**

- Total number of students = 50
- Number of females = 20
- Number of males = Total number of students - Number of females
- Number of males = 50 - 20 = 30

i) Fraction of males in the class:

[tex]\[
\frac{\text{Number of males}}{\text{Total number of students}} = \frac{30}{50} = \frac{3}{5}
\][/tex]

ii) Percentage of females in the class:

[tex]\[
\left(\frac{\text{Number of females}}{\text{Total number of students}}\right) \times 100 = \left(\frac{20}{50}\right) \times 100 = 40\%
\][/tex]

Answer :

Sure! Let's break down the solution step by step for this question.

1. Total Number of Students:
- It's given that there are a total of 50 students in the class.

2. Number of Female Students:
- It's mentioned that there are 20 female students in the class.

3. Number of Male Students:
- To find the number of male students, subtract the number of female students from the total number of students:
[tex]\[
\text{Number of male students} = 50 - 20 = 30
\][/tex]

4. Fraction of Males in the Class:
- The fraction of males in the class is the number of male students divided by the total number of students:
[tex]\[
\text{Fraction of males} = \frac{\text{Number of male students}}{\text{Total number of students}} = \frac{30}{50} = 0.6
\][/tex]

5. Percentage of Females in the Class:
- To find the percentage of females, divide the number of female students by the total number of students and multiply by 100:
[tex]\[
\text{Percentage of females} = \left(\frac{\text{Number of female students}}{\text{Total number of students}}\right) \times 100 = \left(\frac{20}{50}\right) \times 100 = 40\%
\][/tex]

So, the fraction of males in the class is [tex]\(0.6\)[/tex], and the percentage of females is [tex]\(40\%\)[/tex].
