Worked Solution
Step 1: Weight of 1 clip = 2.45 ÷ 1 000 = 0.00245 kg.
Step 2: Weight of 10 clips = 0.00245 × 10 = 0.0245 kg.
Step 3: Ratio = 2.45 ÷ 0.0245 = 100.
Alternative: 1 000 clips ÷ 10 clips = 100, so the carton is 100 times as heavy.
Shortcut: Dividing by 1 000 then multiplying by 10 is the same as dividing by 100.
Correct answer: 100 times
