The importance of lining up the decimals is so you can just add from bottom to top it makes things a lot easier.
That is because if you don't, you will get the wrong answer. It is ALWAYS important to LINE up the decimals.
You do not, but it is easier.
Line up the decimal points and then subtract one from the other.
It is important for you to line up the decimals vertically the way I did above so that you can keep track of the place-value position of the digits.
The question cannot be answered because there are an infinite number of decimals between any two points!

Line up the numbers in such a way that the decimal points are aligned. . Example: 567.89 - 23.4 567.89 - 23.4 ===== 544.49

It is irrelevant if multiplying or dividing decimal numbers. For addition and subtraction it is not sufficient: you need to line up the decimal points as well as the digits according to their place values. If you intend to simply align the decimal points then you may as well not bother. This is to ensure that addition or subtraction is carried out for digits with the same place value.
3.8 + 1.16 = 4.96 When adding decimals, line up the decimal points: 3.8 1.16 + ----- 4.96

Yes you do that is very important when doing a decimal problem.* * * * *It is important for other basic binary operations but NOTmultiplication.
You line up the decimals with the thousandths and put the decimal straight down from where it is and just add with the decimal in the same spot.
First, you draw a number line. You then make points for the counting numbers, and place the mixed numbers and decimals between these points, getting their own points and labels.
line up the numbers and decimals multiply regularly then bring the decimal down
