To find the percentage change from 48 to 25, we need to first calculate the difference between the two numbers.

Step 1: Difference = Final Value - Initial Value

Difference = 25 - 48

Difference = -23

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 = |-23|

Absolute Difference = 23

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

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

Percentage Change = (23 / 48) x 100

Percentage Change = 47.92%

Therefore, the percentage change from 48 to 25 is -47.92%. This means that there was a decrease of 47.92% from 48 to 25.
