Interpretation: (2/31) × (6 1/20)
Steps:
- Convert the mixed number: 6 1/20 = (6×20 + 1) / 20 = 121/20
- Multiply: (2/31) × (121/20) = (2×121) / (31×20) = 242/620
- Simplify: 242/620 = 121/310 (since both divisible by 2)
Result: 121/310 ≈ 0.3903
Optional cross-cancellation (before multiplying): (2/31) × (121/20) → (1/31) × (121/10) = 121/310.
