If you have no clue about how decimals work then getting an estimate for the answer gives you an order of magnitude which can help in placing the decimal. But if you are even a bit clued up, estimating will not be necessary.
By estimating the product it gives an indication of how big the final answer should be; knowing this, the decimal point can be put in to give an answer of the correct size. For example if the product estimate is 125 and the actual answer (without the decimal point) is 136728, then the decimal point needs to be inserted to make the answer about 125; the place is therefore after the 136, making the answer 136.728 (= 5.4 x 25.32 ≈ 5 x 25 = 125)
One decimal place. 3.9 is the quotient.
44/22 = 2 so the decimal point should be placed after the first digit (which is a 1).
hundredths place in a decimal is at the second place at the right of the decimal point.
The second decimal place to the right of the decimal point is called the hundredths place
Estimating will give an indication of the order of magnitude of the answer. The decimal point determines the order of magnitude.
Yes, that's true.
Estimating quotients gives an indication of the order of magnitude of the answer. That is, whether the answer is in units, or tens, or hundreds, thousands and so forth. Basic understanding of the placement of the decimal point should then be a trivial exercise.
Learning to estimate products is very helpful because it helps with teach you how to learn how to do your taxes and etc.
Estimating help determine the order of magnitude of the answer. It is, therefore, a simple matter to place the decimal point is such a way that the order of magnitude of the calculated answer matches that of the estimate.

Estimating the number 684.575 to one decimal place gives you 684.6 which is very close.
You can use estimation and place value to help you figure out where to place the first digit.
Divide as normal, but make sure to place the decimal point in the quotient directly above the decimal point in the dividend.
the decimal place in the quotient or product should be based in the decimal place of the given with the least significant figures
