Percentages practice problems - page 6 of 99
Percentages are a way to express a number as a fraction of 100. They are often used to express a proportion or rate, such as a percentage of total sales or a percentage increase or decrease in a value. For example, if a product sells 25 out of 100 units, the percentage of units sold is 25%, which can also be written as 0.25 or 25/100.Percentage points, also known as percentage point change or "pp" for short, is the difference between two percentages. It is often used to express the change in a variable over time or between two groups. For example, if a company's profits increased from 10% to 20% over a year, the percentage point change would be 10 percentage points (20% - 10% = 10%).
