I prefer to use compatible numbers because by using this method it is easier to make a sum mentally. This is true because compatible numbers are close in value to the actual numbers. For a better understanding, let's take an example:

64 ÷ 4 = 16
So, we have used mental arithmetic to solve a more complex problem.
