Answer 1

Answer:

Girls =66

Boys=54

Boys percentage=45%

Explanation:

Given that;

There are 120 student

percentage of girls is 55%

let girls be =x

x=percentage* total no 'of students

x=55/100*120

x=66

Boys=total no'of students-no' of girls

=120-66

=54

For boys percentage;

No'of students=boys percentage*total no'of students in the school

54=x/100*120

54=6x/5

6x/5=54 ( LHS to RHS and RHS to LHS)

6x=54*5

x=54*5/6

x=9*5

x=45

Therefore,Girls=66

Boys=54

percentage of boys= 45%
