Numerical Ability - Simplification & Approximation
Simplify: (9/14) × (7/18)
Simplify: (9/14) × (7/18)
easy Q2 of 15
Step-by-Step Solution
Step 1: Cancel common factors
Cancel 9 with 18 → 1 and 2. Cancel 7 with 14 → 1 and 2.Step 2: Multiply the simplified fractions
Expression becomes (1/2) × (1/2) = 1/4.Final Answer:
1/4 → Option B.Quick Check:
(0.6429 × 0.3889 ≈ 0.25) → 1/4 ✅
Quick Trick: Cancel crosswise before multiplying to avoid big numbers.
Common Mistakes:
- Cancelling within a single fraction only instead of cross-cancelling.
