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