Question

for every 6 girls on the softball team there are 9 boys on the baseball team if there are 50 students on both teams how many are girls

Answer 1

Key info-there are nine boys for every six girls on the softball team

9/6

9(3)=27. 6(3)18

18+27=45 5 more to go

if there is 50 students on each of the teams

9(5)=45
6(8)=48

As one can see,they both cannot multiply up to 50,but they round up.

Answer 2

Let g = number of girls and b = number of boys, then:-

g + b = 50 ..........(1)

and

for every girl there is 1.5 boys so:-

b = 1.5g...........(2)

Substitute for b in equation (1):-

1.5g + g = 50

2.5g = 50

g = 20

Answer is there are 20 girls
