Worked Solution

Step 1: Convert each length to centimetres so the units match. 1 m = 100 cm. Step 2: Ribbon A: 1 m 25 cm = 100 + 25 = 125 cm. Ribbon B: 90 cm. Ribbon C: 1 m 9 cm = 100 + 9 = 109 cm. Step 3: Compare: 125 cm > 109 cm > 90 cm. Ribbon A is the longest. Answer: Ribbon A

Correct answer: Ribbon A
