Question

in a class of 35 students, the number of girls is two-fifth of the boys. find the number of girls in the class please explain step by step​

Answer 1

Total no of students:- 35
Now in a fraction,number of girls = 2/5 of total boys
Now let number of boys be x.
Therefore no. Of girls = (2/5)*x
Total student= (2/5)*x+x = 7x/5
Now 7x/5= 35
X=25
No of boys = x= 25
Therefore no. Of girls= 35-25=10

Answer 2

Answer:-

There Are 10 girls in the class.

Explanation:-

Given:-

• Total number of students in a class = 35.
• 2/5 of total boys in the class are girls.

To Find:-

• The number of girls in the class.

So,

Let the number of boys in the class be x.

Now,

According To The Question,

↦ 2/5 of boys + boys = Total students.

↦ (2/5 × x) + x = 35.

↦ 2x/5 + x = 35.

↦ (2x + 5x)/5 = 35.

↦ 7x = 35 × 5.

↦ 7x = 175.

↦ x = 175/7.

↦ x = 25 = Number of boys.

Also,

↦ Total Boys + Total Girls = Total students.

↦ 25 + Total girls = 35.

↦ Total girls = 35 - 25.

↦ Total girls = 10.

Therefore total number of girls in the class are 10.
