Frequently Asked Questions (FAQs)

Use the basic formula:
Percentage=(PartWhole)×100
(Example: 25 is what % of 50? → (25/50) × 100 = 50%)
Q2: How do I add or subtract a percentage?
- To add X%: Multiply by (1 + X/100)
(Example: Add 15% to 80∗∗→80×1.15=∗∗92) - To subtract X%: Multiply by (1 – X/100)
(Example: Subtract 20% from 150∗∗→150×0.80=∗∗120)
Q3: What’s the difference between percentage increase and decrease?
- Increase: New value > Original → Positive % (e.g., +25%)
- Decrease: New value < Original → Negative % (e.g., -10%)
Q4: Can I calculate reverse percentages?
Yes! If 30 is 25% of X, then:
X=300.25=120
