Question

Solve the following problem (to the nearest thousandth). 9.42 + 0.295 + 51.7 =

Answer 1

Line up the decimal places.
Carry numbers over when you need to.

9.42
+ 0.295
+ 51. 7
------------
61.415

Answer 2

The answer is 61.415

Explanation:

In order to determine the solve, we have to know the notation of the number for every place in a rational number.

Also, we have to know that if we want to round a number in a specific position, there is a rule that says:

If the number to the right of the position is greater or equal than 5, you have to increment the number on the position in one digit. Otherwise, you have to maintain the original number.

I have attached an image that shows the notation of the number for every place in a rational number.

So, in this case, the addition is:

9.42+0.295+51.7=61.415

Then, if we round the number to the nearest thousandth, according to the image, we do not have to do nothing, because the original number has three digits, that it means, the number is already in the nearest thousandth.

Therefore, the solve is 61.415
