Problem: Find the percentage change of 10 minutes to 12 minutes.

Solutions:

First thing to do is to find out how many minutes added to 10 minutes. SO let’s
subtract 12 minutes and 10 minutes

=> 12 minutes – 10 minutes = 2 minutes.

Thus, 2 minutes is added now, let’s follow the formula

=> 2 minutes / 10 minutes = 0.2 minutes

=> 0.2 minutes * 100% = 20%

Thus, the percentage rate changes is about 20% of the given number of minutes.
