The 12 girls at Suzie’s volleyball camp have decided to wear their camp ID’s on loops of string around their necks. If each girl needs 1 2 yard of string, how much string do they need in all? Suzie did this work to solve the problem: 12 1 ÷ 1 2 = 12 1 × 2 1 = 24 1 = 24 yards of string Did Suzie solve the problem correctly? No. She should have multiplied 12 and One-half to solve. No. She did not multiply the numerators correctly. No. She did not simplify 24 Over 1 correctly. Yes. Her work is correct.
