Answer
Correct Answer: Left product is larger
Explanation
Problem restatementDecide which of the two given decimal products has the greater value.
Given data
- A = 0.1667 × 0.8333 × 0.3333
- B = 0.2222 × 0.6667 × 0.1250
Concept/ApproachEstimate each term to familiar fractions (0.1667 ≈ 1/6, 0.8333 ≈ 5/6, 0.3333 ≈ 1/3, 0.2222 ≈ 2/9, 0.6667 ≈ 2/3, 0.1250 = 1/8), or compute directly with careful decimals.
Step-by-Step calculation A ≈ 0.1667 × 0.8333 = 0.1389 (approx), then × 0.3333 ≈ 0.0463 B ≈ 0.2222 × 0.6667 = 0.1481 (approx), then × 0.1250 ≈ 0.0185 Therefore, A ≈ 0.0463 and B ≈ 0.0185 ⇒ A > B
Verification/AlternativeFractional check: (1/6)(5/6)(1/3) = 5/108 ≈ 0.046296, while (2/9)(2/3)(1/8) = 4/216 = 1/54 ≈ 0.018519. Left is clearly larger.
Common pitfalls
- Assuming equality because both look like products of small decimals.
- Rounding too coarsely; here the order of magnitude differs by about 2.5×.
