The answer to your question is 85 7th graders.How is it 85?

A ratio of 17 : 23   means there are 40 equal parts

 

So   (17/40) * 200  =   85   7th graders

 

And  (23/40) * 200  =  115    8th graders

17:23....added = 40

17/40(200) = 3400/40 = 85 (7th graders)
23/40(200) = 4600/40 = 115 (8th graders)
