Question

Answer please? I need it for homework

Answer 1

boys = 150

girls = 350

Explanation:

I'm not sure what a tape diagram is, but I can get the answer.

Let b = boys

Let g = girls

3/7 = b/g

3/7 = b/(b + 200)

3(b + 200) = 7b

3b + 600 = 7b

600 = 4b

b = 600/4

b = 150

g= 150 + 200

g = 350
