Calculating the Percentage Change

To find the percentage change when a value is increased from 40 to 56, you can follow these steps:

1. First, determine the difference between the new value and the original value. In this case, you subtract the original value (40) from the new value (56):

Difference = New Value – Original Value = 56 – 40 = 16

2. Next, to find the percentage change, you divide the difference by the original value (40) and then multiply by 100 to convert it into a percentage:

Percentage Change = (Difference / Original Value) x 100

This translates to:

Percentage Change = (16 / 40) x 100

3. Now, calculate the fraction:

Percentage Change = 0.4 x 100 = 40%

Conclusion

When 40 is increased to 56, the percentage change is 40%.
