Question

Add the following $18,200.35,11.72\text{ and 2}\text{.3}$.

Answer 1

Hint: We have given numbers and we have to add them. To solve this question first we make all numbers to like decimals by adding zeros after the decimal point. Then by using column addition we solve the question to get the desired answer.

Complete step by step answer:
We have been given the numbers $18,200.35,11.72\text{ and 2}\text{.3}$.
We have to find the sum of all.
Now, we have three decimal numbers and one whole number.
Now, let us convert them $18$ into decimal numbers.
We can write $18$ as $18.00$.
Also, we can write $2.3$ as $2.30$ to make it like a decimal with two decimal places, and hence decimal places will be equal to other numbers.
Now, we can find the sum using column addition. In column addition, we add digits of ones place first then tens place digits and so on.
So, we have $18.00+200.35+11.72+2.30$
Let us add the digits from the right-hand side and solve the above addition we get
$\Rightarrow 232.37$
So we get the addition of \[18.00+200.35+11.72+2.30=232.37\]
In decimal addition the decimal point is put at the same place i.e. in this question decimal is put after two digits from the right-hand side.

Note:
 The point to remember in decimal addition is that we can add like decimals. So, convert all given numbers into decimal having the same number of decimal places by adding zeros after the decimal point. Also, remember to put the decimal point in the answer in the right position. The addition of whole numbers is performed directly, there is no need to put zeros in addition to whole numbers.
