To do percentages, you first need to understand what they represent. Percentages are a way to express a portion or fraction of a whole number out of 100.
To calculate a percentage, follow these steps:
Step 1: Convert the percentage to a decimal - Divide the given percentage by 100. For example, if you have 25%, divide 25 by 100 to get 0.25.
Step 2: Multiply the decimal by the whole number you want to find the percentage of. For example, if you want to find 20% of 80, multiply 0.20 by 80 to get 16.
Step 3: If you want to find the percentage increase or decrease, use the following formula:
Percentage Change = (New Value - Old Value) / Old Value * 100
For example, if the original value was 100 and the new value is 120, the percentage increase would be ((120 - 100) / 100) * 100 = 20%.
Remember, percentages can be used in many different situations, such as calculating discounts, tax amounts, or expressing proportions.
