How does estimating the answer help you to know that you placed the decimal point in the sum correctly?

It doesn't really. If you are a competent user of arithmetic operations on decimal numbers then this will only mean additional calculations simply to confirm something which you would have done correctly anyway. And if you are not competent, then who is to say that your estimation is more likely to be correct?

Estimating the answer helps you to know if you placed the decimal point correctly in the sum because you can quickly check if your estimated answer matches closely with the actual answer. If they are similar, it suggests that the decimal point was placed correctly. If they are significantly different, it may indicate an error in placing the decimal point.

How does estimating help us place the decimal point in the quotient?
Estimating will give an indication of the order of magnitude of the answer. The decimal point determines the order of magnitude.
How can you use estimation to determine whether you have placed the decimal point correctly in the product?
A reasonable estimate will give an indication of the order of magnitude of the number. The order of magnitude is determined by the decimal point and so knowing the order can help in placing it.
What is the maximum number of decimal places allowed after a decimal point?
An infinite amount of numbers can theoretically be placed after the decimal point.
Where should a decimal point be placed in the answer of addition and subtraction problems?
Where the decimal is placed you just have to bring it straight down.
What are two methods for determining the placement of the decimal point in the product?
When you multiply decimals, the decimal point is placed in the product.
How can estimating quotients help you place the decimal correctly?
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.

How can estimating products help you to place a decimal correctly?
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)
How does estimation help you place the decimal point in a product correctly?
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.
How can you use estimation to check that you have placed the decimal point correctly in your product?
An estimate will give an indication of the order of magnitude of the answer. The decimal point determines the order of magnitude and so, if the two are in agreement, then the decimal point has been placed in the right place. However, if you did your arithmetic properly then there would be no need to do the extra calculations required for an estimate.

Why should the decimal point be placed after the multiplication is complete?
Because until that time there is nothing to put the decimal point in!
What are two methods for determining the placement of the decimal point in the product?
When you multiply decimals, the decimal point is placed in the product.
What is the meaning of decimal point?
a dot placed after the figure representing units in a decimal fraction.
What is the definition of decimal point?
a dot placed after the figure representing units in a decimal fraction.
