To find X percent of Y, convert X to a decimal by dividing by 100, then multiply by Y. Example: 20% of 500 is (20/100) * 500 = 100.
The formula for percentage increase is: ((New Value - Old Value) / Old Value) * 100. This gives you the percentage growth from the original value.
Divide the part (X) by the whole (Y), then multiply by 100. Example: 25 is what % of 200? (25 / 200) * 100 = 12.5%.
