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:

Suppose you have two numbers, namely 640 and 40. These two numbers are compatible for division because:

64 ÷ 4 = 16

So, we have used mental arithmetic to solve a more complex problem.

Change 4 feet to inches.

You need to know that for every feet, there are 12 inches. So, if you have 4 feet, you just multiply 4 by 12 and you will get 48 inches. Note that the feet unit is larger than inches.
