To find the percentage change from 12 to 15, we need to first calculate the difference between the two numbers.
Step 1: Difference = Final Value - Initial Value
Difference = 15 - 12
Difference = 3
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 = |3|
Absolute Difference = 3
Step 3: Now, we can calculate the percentage change using the formula:
Percentage Change = (Absolute Difference / Initial Value) x 100
Percentage Change = (3 / 12) x 100
Percentage Change = 25%
Therefore, the percentage change from 12 to 15 is 25%. This means that there was an increase of 25% from 12 to 15.
