To find the percentage change from 10 to 11, we need to first calculate the difference between the two numbers.

Step 1: Difference = Final Value - Initial Value

Difference = 11 - 10

Difference = 1

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 = |1|

Absolute Difference = 1

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

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

Percentage Change = (1 / 10) x 100

Percentage Change = 10%

Therefore, the percentage change from 10 to 11 is 10%. This means that there was an increase of 10% from 10 to 11.
