Understanding Percent Increase

Percent increase is a measure of the change in a value over a specific period. It is calculated as the difference between the new and old values, divided by the old value, and then multiplied by 100 to express it as a percentage. In this case, we want to find the percent increase from 52.252.2 to 78.378.3.

Formula for Percent Increase

The formula for percent increase is:

Percent Increase = ((New Value - Old Value) / Old Value) × 100

Calculating Percent Increase

To calculate the percent increase from 52.252.2 to 78.378.3, we will use the formula above.

Step 1: Find the difference between the new and old values

New Value = 78.378.3 Old Value = 52.252.2

Difference = New Value - Old Value = 78.3−52.278.3 - 52.2 = 26.126.1

Step 2: Divide the difference by the old value

Difference ÷ Old Value = 26.1÷52.226.1 ÷ 52.2 = 0.5

Step 3: Multiply by 100 to express as a percentage

Percent Increase = (Difference ÷ Old Value) × 100 = 0.5 × 100 = 50%

Conclusion

The percent increase from 52.252.2 to 78.378.3 is 50%. This means that the value increased by 50% from 52.252.2 to 78.378.3.
