fractions -in a school,3/5 of the students are girls, number of boys in the school is 200. find the total number of students in the school
If 3/5 of the students (you can also think this as 3 out of 5 students) are girls, how many of the 5 students are boys? Present in fraction form. This is the simplified or reduced fraction.
fraction = part/whole = number of boys/ number of students
Set the reduced fraction = actual fraction.
reduced number of boys/ reduced number of students
= actual number of boys/ actual number of students

In a school 8/5 of the total students are boys. If there are 360 girls, then the number of students in the school is?
A don’t know
To find the total number of students in the school, you need to determine the fraction represented by the boys out of the entire student population and then find the total number of students using that fraction.
Given that 3/5 of the students are girls, this means that the remaining 2/5 must be boys. Since the number of boys is given as 200, we can set up the equation:
2/5 * Total number of students = Number of boys
To find the total number of students, we need to solve for the unknown variable. We can rearrange the equation to isolate the total number of students:
Total number of students = Number of boys / (2/5)
Now we can substitute the value of the number of boys into the equation:
Total number of students = 200 / (2/5)
To divide by a fraction, we can multiply by its reciprocal:
Total number of students = 200 * (5/2)
Performing the multiplication:
Total number of students = 1000 / 2
Total number of students = 500
Therefore, the total number of students in the school is 500.
