Given the following expression:

[tex]\[ \frac{1}{2} \times \frac{6}{7} \times 9 \times \frac{18}{147} = \frac{3}{14} \][/tex]

Question:
The total number of students in a motor's classroom is 45. If [tex]\(\frac{1}{5}\)[/tex] of the total students are girls, find the total number of girls.



Answer :

Sure, let's solve this problem step by step.

The total number of students is given as 45. We need to find the total number of girls, given that girls constitute [tex]\(\frac{1}{5}\)[/tex] of the total number of students.

1. Understand the fraction given:
- The fraction [tex]\(\frac{1}{5}\)[/tex] represents the part of the total number of students who are girls.

2. Calculate the number of girls:
- To find the number of girls, we multiply the total number of students by the fraction of girls.
- So, we multiply [tex]\(45\)[/tex] by [tex]\(\frac{1}{5}\)[/tex].

3. Perform the multiplication:
- [tex]\(45 \times \frac{1}{5} = 9\)[/tex].

Therefore, the total number of girls is [tex]\(9\)[/tex].
