Which formula is used to calculate percent decrease?

To calculate percent decrease, the correct formula involves determining the difference between the original value and the new value, dividing that difference by the original value, and then multiplying by 100 to convert it into a percentage. This approach accurately captures the extent of the decrease relative to the original value.

The formula begins with taking the original value and subtracting the new value to find the actual decrease in value. By dividing this decrease by the original value, you can understand how significant the decrease is in relation to where you started. Multiplying by 100 allows you to express this ratio as a percentage, making it easier to interpret.

Using this method provides a clear and accurate representation of the decrease, which is crucial for various applications, such as in finance, sales reporting, or any scenario where understanding changes in value is important.
