## 433.44.4 Hint:

## The correct answer is: 3.4

### Now as we know that here we have to find the step by breaking one number. The fact that there are no steps to memorise is one of the best things about mental math. The "friendly number" addition approach facilitates working with large numbers. This is due to the fact that we are, in essence, decomposing the problem into more manageable components.Now we have given two decimal numbers 11.2 and 7.8 and we have to find the difference.11.2 – 7.8We will add 0.2 to both the numbers(11.2 + 0.2) - (7.8 + 0.2)11.4 - 8Finally, we get: 3.4

Here the concept of Break Apart Numbers is used where a number is divided in two parts to make addition easy. The concept of friendly numbers is also used so that it becomes easy for addition or subtraction purpose. So, the difference we get when 7.8 is subtracted from 11.2 is 3.4.
