Question

There are 320 students in a school.

Answer 1

Answer:

so total boys = 178

total girls = 142

fraction of students in school which are boys

=》178 / 320

=》89 / 160

Step-by-step explanation:

let the number of boys be x

and the number of girls be y

x + y = 320 - ( equation 1 )

( since, total students = total girls + total boys )

and here,

x = y + 36 - ( equation 2 )

( because there are 36 more boys than girls )

so,

putting the value of x from equation 2 into equation 1

=》x + y = 320

=》y + 36 + y = 320

( since, x = 36 + y )

=》2y = 320 - 36

=》y = 284 / 2

=》y = 142

so we get total girls = y = 142

and, we know

=》x = y + 36

=》x = 142 + 36

=》x = 178

so total number of boys = x = 178

Answer 2

196/320 is fraction
