To calculate a percentage, you first need to convert the part to a fraction by dividing it by the whole. For example, if 25 out of 100 students in a class received an A grade, the percentage of students who received an A is 25/100, or 0.25. To express this as a percentage, multiply by 100 to get 25%.

Rates of change, such as increases or decreases in prices, populations, or percentages themselves, are commonly represented by percentages. For example, if a product’s price increases from $10 to $12, the percentage increase is (12-10)/10 x 100%, or 20%. If a country’s population increases from 100 million to 110 million, the percentage increase is (110-100)/100 x 100%, or 10%.

Percentages are also commonly used to represent proportions, such as the percentage of a total that belongs to a certain category. For example, if a store sells 100 apples and 60 of them are red, the percentage of red apples is 60/100 x 100%, or 60%.

## What is percentage formals in deferent deferent ways?

Depending on the context and the given information, percentages can be calculated and expressed in different ways. The most common formulas used to calculate percentages are as follows:

**Percentage as a fraction:** Percentage can be expressed as a fraction by dividing the percentage by 100. For example, 25% is equivalent to 25/100 or 0.25 as a fraction.

**Percentage change:** Percentage change is the percentage difference between two values. It is calculated by taking the difference between the new and old values. Dividing it by the old value, and multiplying by 100. For example, if the price of a product increased from $10 to $12, the percentage change is [(12-10)/10] x 100% = 20%.

**Percentage of a whole:** To calculate the percentage of a whole, divide the part by the whole and multiply by 100. For example, if a class has 25 boys out of 100 students, the percentage of boys in the class is (25/100) x 100% = 25%.

**Percentage increase or decrease:** To calculate the percentage increase or decrease. Divide the difference between the new and old values by the old value and multiply by 100. For example, if the number of students in a class increased from 100 to 120, the percentage increase is [(120-100)/100] x 100% = 20%.

**Percentage point change:** Percentage point change is the difference between two percentages. For example, if the percentage of students who passed a test increased from 80% to 85%. the percentage point change is 85% – 80% = 5%.
