Answers

Let the number of girls be x
Then boys = x+4
Total number of students= 40= x+x+4
2x+4=40
2x= 36
x= 18
number of girls= 18
Then boys = x+4
Total number of students= 40= x+x+4
2x+4=40
2x= 36
x= 18
number of girls= 18

40 divided by 2 equals 20
20+4=24
24=boys
40-24=[16]
NUMBER OF GIRLS= 16
20+4=24
24=boys
40-24=[16]
NUMBER OF GIRLS= 16
