Question

.In school ,there are 3 girls for every 2 boys . There are 650 students in total . How many students are girls ?

Answer 1

The number of girls = 390

Given:

In a school, there are 3 girls for every 2 boys.

There are 650 students in total.

To find:

How many students are girls?  

Solution:

Given that

In a school, there are 3 girls for every 2 boys

This means the ratio of girls and boys = 3: 2

Let 3x and 2x be the number of girls and boys in the school [ Since the ratio of girls and boys is 3: 2 ]    

From the given data, the number of students = 650

=> 3x + 2x = 650

=> 5x = 650

=> x = 650/5

=> x = 130  

Number of girls = 3x = 3(130) = 390

Therefore,

The number of girls = 390

Answer 2

Answer: There are 390 girls in the school.

Let x be the number of girls in the school.

Then, there are 2x/3 boys in the school.

Since the total number of students is 650, we can write an equation:

                                  x + 2x/3 = 650

Combining like terms:

                                     5x/3 = 650

Solving for x:

                                          x = 390

So there are 390 girls in the school.
