medium Q8 of 15
Step-by-Step Solution
Step 1: Multiply the factors
52.7 × 3.14 = 165.478.Step 2: Divide by 2
165.478 ÷ 2 = 82.739.Step 3: Round to one decimal place
Round → 82.7.Final Answer:
82.7 → Option C.Quick Check:
52.7 × 3 ≈ 158.1; half of 158.1 = 79.05; adding the 0.14×52.7 contribution (~7.38) → ≈82.4–82.8 range ✅
Quick Trick: Carry out multiplication and division first, then round the final result.
Common Mistakes:
- Rounding intermediate steps prematurely and losing precision.
