Answer: Step-by-step explanation: boy count is 1476 Explanation: There is an important difference between the way counts are viewed in ratio to that in fractions. The ratio of boys : girls → 4 : 5 so you have 4 boys and 5 girls making the whole count 4 + 5 = 9 in its simplest form. So to change the ratio proportion into fraction proportion we have: boys → 4 9 of the whole. girls → 5 9 of the whole. It is given that the whole is 3321 therefore the count of boys is: 4 9 × 3321 = 1476 Reply
