Question

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 StartFraction 24 Over 1 EndFraction correctly. Yes. Her work is correct.

Answer 1

Answer:

No. She should have multiplied 12 and One-half to solve

6 yards

Step-by-step explanation:

Number of girls = 12

Each girl needs = 1/2 yard of strings

Suzie workings:

12/1 ÷ 1/2

= 12/1 × 2/1

= 24/1

= 24 yards

No. She should have multiplied 12 and One-half to solve

Correct workings:

Total strings needed for 12 girls = 12 × 1/2 yards

= (12*1)/2

= 12/2

= 6 yards
