Why do you need to line up the decimal points before comparing and ordering with decimals?
Because the number in decimal form has a different value based on their position from the decimal point. Every one number left of decimal point it will be valued 10 times. If you don't line them up you can compare them because they might have a different value and you will end up messing your calculation.

What comes before 0 in decimals?
Any negative decimal comes before zero in decimals.
Ordering decimals from greatest to least?
Sure thing, honey. When ordering decimals from greatest to least, you start by looking at the whole numbers before the decimal point. If they're the same, you move on to the tenths place, then the hundredths place, and so on. It's like lining up your ducks in a row, but with numbers. Easy peasy, lemon squeezy.
When multiplying decimals how do you determine where to place the decimal in the answer?
If the two multiplicands have X and Y digits after the decimal place then their product (before removing any trailing 0s) has (X+Y) digits after the decimal point.
How many zeros are in a trillion with decimals?
There are 12 0s in a trillion - before the decimal point. Since a trillion is a whole number, there is no need for 0s after the decimal point. If you do have 0s after the decimal point, there can by any number that you like and so the question cannot be answered.
What do you do before dividing by a decimal?
Move the decimal point
What do you need to line up decimal points before comparing and ordering numbers with decimals?
You do not, but it is easier.

Why do you need to line up the decimal points before comparing and ordering numbers with decimals?
This answer is irrelevant because you did not explain yourself, the correct answer is,"Its important so you can separate whole numbers for parts of whole numbers."
What comes before 0 in decimals?

What decimal is before 0.45?
There is no such number because decimals are infinitely dense. That is, between any two decimals, there are infinitely many decimals.

What is the key of adding and subtracting decimals?
The key would be to add (00.) before your decimal. IE 00.41 + 00.95 = 01.36
When multiplying decimals how do you determine where to place the decimal in the answer?
If the two multiplicands have X and Y digits after the decimal place then their product (before removing any trailing 0s) has (X+Y) digits after the decimal point.
How do you decimals to the nearest whole number?
Look at the digit after the decimal point. If it is bigger than 5, then add one to the last digit BEFORE the decimal point otherwise don't add. Then delete the decimal point and everything after it.
