Percentage Change between V1 and V2
Answer


Solution:

To find the percentage change from 140 to 100, we need to first calculate the difference between the two numbers.

Step 1: Difference = Final Value - Initial Value

Difference = 100 - 140

Difference = -40

Step 2: Next, we need to find the absolute value of the difference. This is because percentage change is always calculated as a positive value.

Absolute Difference = |Difference|

Absolute Difference = |-40|

Absolute Difference = 40

Step 3: Now, we can calculate the percentage change using the formula:

Percentage Change = (Absolute Difference / Initial Value) x 100

Percentage Change = (40 / 140) x 100

Percentage Change = 28.57%

Therefore, the percentage change from 140 to 100 is -28.57%. This means that there was a decrease of 28.57% from 140 to 100.
