Calculating the Number of Girls in the Class

To calculate the number of girls in the class, we can start by finding out how many students in the class are boys. Then, we can use this information to determine the number of girls.

Given that 40% of the class are boys, we can calculate the number of boys in the class using the following formula:

Number of Boys = Total Number of Students × Percentage of Boys

Using this formula, we can find the number of boys in the class.

Calculation

Number of Boys = 35 (Total Students) × 40% (Percentage of Boys)

Number of Boys = 35 × 0.40

Number of Boys = 14

So, there are 14 boys in the class.

Now, to find the number of girls in the class, we can subtract the number of boys from the total number of students:

Number of Girls = Total Number of Students - Number of Boys

Number of Girls = 35 - 14

Number of Girls = 21

Therefore, there are 21 girls in the class.
