Question

If there are 60 students in a classroom, given that 15 are boys. find percentage of girls in the classroom.​

Answer 1

75%

Explanation:

There are 60 students in the classroom.

15 are boys.

Find the number of girls:

(total no. of students) - (no. of boys) = (no. of girls)

60 - 15

= 45

There are 45 girls in the classroom.

Find the percentage of girls in the classroom:

(no. of girls)/(total no. of students) × 100

45/60 × 100

9/12 × 100

900/12 = 75

The percentage of girls in the classroom is 75%.

Answer 2

75 %

Explanation:

Total = 60

Boys = 15

Girls = 60-15

=> 45 girls

Percentage of Girls:

=>
`(45)/(60) * 100`

=>
`(450)/(6)`

=> 75 %
