Answer:
72
Step-by-step explanation:
If you multiply both sides of this equation by 9, you get t=8*9=72. Hope this helps!
Ratio is 5girls:7boys with total 72 students
5+7= 12
72➗12= 6
6(5:7)= 30 girls : 42 boys
New ratio is 3:4 with 48 boys
48➗4= 12
So for girls 3x12= 36
<span>So started with 30 girls ended with 36 girls... 6 girls joined band during the school year.</span>

I simply used a calculator and did 120/1, 120/2, 120/3 etc.. and found these numbers that work together.
M + e + f = 11
e = 1/5m
f = 3m
m + 1/5m + 3m = 11 <== ur equation
5/5m + 1/5m + 15/5m = 11
21/5m = 11
m = 11 / (21/5)
m = 11 * 5/21
m = 55/21
m = 2.619 rounds to 2.62...milk
e = 1/5m
e = 1/5(2.62)
e = 0.53 .....eggs
f = 3m
f = 3(2.62)
f = 7.86...fabric softener
