Answer:
boys- 18
girls- 30
Step-by-step explanation:
number of boys = 3/5number of girls (3/5x)
number of girls = x
total number = 48
3/5x + x = 48
5x+3x/5 = 48 add 3/5x to x, we get 8x/5
(8x/5 = 48) 5 then multiply both sides by 5 to cancel the denominator
1/8 (8x = 240) divide both sides by 8 or multiply 1/8 to find the value of x
x= 30
3/5 of 30 is equal to 18
30+18=48
