Simplify: (50% of 360 + √144) ÷ (3/4 of 16)
medium Q6 of 15
Step-by-Step Solution
Step 1: Percent:
50% of 360 = (50/100) × 360 = 0.5 × 360 = 180.Step 2: Root:
√144 = 12.Step 3: Numerator:
180 + 12 = 192.Step 4: Denominator:
(3/4) of 16 = (3/4) × 16 = 3 × 4 = 12.Step 5: Division:
192 ÷ 12 = 16.Final Answer:
16 → Option C.Quick Check:
16 × 12 = 192 ✅
Quick Trick: Use halves/quarters for quick percent + fraction evaluation.
Common Mistakes:
- Treating 3/4 incorrectly or skipping the root evaluation.
