There are 105 members of the high school marching band. for every 3 boy there are 4 girls. how many girls are in the band

for every 3 boys, there are 4 girls. we can rephrase this to say: out of each group of 7 band members, 3 are boys and 4 are girls. therefore the ratio of boys: bandmembers is 3: 7, 3/7.

as a proportion (3 boys)/(7 members) = (x boys)/(105 members)

you can cross multiply to solve this equation.

answer:

3 boy 4girls

hope this and for a little humor i am groot.

the answer would be c:   ax + b = ax + c
