What is 0.3 × 0.4 × 0.5?
Answer and explanation
Correct answer: C. 0.06
- Step 1: Multiply the digits: 3 × 4 × 5 = 60. Step 2. There are three decimal places altogether, so 60 becomes 0.060 = 0.06. Answer: 0.06. Why not the others: 0.6: This puts the decimal point one place too far to the right; there are three decimal places in 3 × 4 × 5 = 60 → 0.060. 0.006: This has one decimal place too many. 1.2: This adds the three numbers instead of multiplying them.
