Question

How do you find the sum of \[2.5 + 2.57 + 3.1\]?

Answer 1

Hint: Here in this question, we have + symbol which represents the addition and we have to add the three numbers. The numbers are in the form of decimal and we write the numbers one below the other where the decimal point should come in orderly and we are going to simplify the given numbers.

Complete step by step answer:
Here in this question, we have to add the numbers. As we know + sign indicates the addition. The numbers are in the form of decimal so we should know the decimal place value system which makes it easy to simplify. The same place value system should be added. In the final answer we should mention the decimal point.
Now consider the three numbers, 2.5 in this number we have one number after the decimal point. in the number 2.57 we have two numbers after the decimal point. in the 3.1 we have one number after the decimal point.
Now we apply the addition to these numbers.
\[2.5 + 2.57 + 3.1\]
on adding we get the solution as
\[2.50 + 2.57 + 3.10 = 8.17\]
Hence we obtained the result for the given question

Therefore the value of \[2.5 + 2.57 + 3.1 = 8.17\]

Note: The addition of any kind of numbers has different procedures. Here the question contains decimal numbers, while adding the decimal number we should take care of decimal points. If we know the place value system of the decimal number it will be easy to add the numbers. In the solution we have to place the decimal point, if we do not mention it the solution is wrong.
