In a chess club, 75% of the members are boys. Of these boys, 8% have hazel eyes. If 6 boys have hazel eyes, how many people are in the chess club
6 boys is 8%of boys, thus 100%of boys is 75 boys.
75% of people accounts for 75 boys, so it's easy to see the other 25% accounts for 25 girls, and that should be enough information to solve the question
Let P be the number of people and B be the number of boys:
We are told: B = 0.75*P
and that 0.08*B = 6
Find B from the second equation and substitute that back into the first equation to find P.
