# Annie spends an average of 2.46 hours on online gaming and 2.44 hours on doing other school activities online each day, 6 days a week. She spends ____________ hrs on internet everyday

## 6 hrs12 hrs5 hrs18 hrs Hint:

## The correct answer is: 5 hrs

### 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.Here we will use some properties which are: Commutative Property of Addition: if a and b are real numbers, then a+b=b+a Associative Property of Addition: if a,b, and c are real numbers, then (a+b)+c=a+(b+c) Compensation Property: It is a mental math strategy for multi-digit addition that involves adjusting one of the addends to make the equation easier to solve. Now we have given 2.46 + 2.44, let's solve this.2.46 + 2.44 = 5 hrs. (Compatible numbers)So, the sum is 5 hours.

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. Some properties like compatible numbers is also used to solve easily. So, the sum is 5 hours.
