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.

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 vector multiplication?
Vector multiplication is one of several techniques for the multiplication of two vectors with themselves. A vector has a magnitude and direction.
Why is the size of a decimal number not necessarily determined by the number of decimal places notated?
Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude.

What is the definition of a magnitude estimate?
Apparently a magnitude estimate is just a estimate just closer to the actual answer.
What is multipliynig decimal?
It is the multiplication of two numbers which are in decimal form.
How can estimating quotient help you to place the decimal correctly?
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.
What is the magnitude estimate for 9796 and 10000?
Their magnitude is ten thousands.
What is the magnitude estimate for 12.2 multiplied by 1.56?
The magnitude estimate for 12.2 multiplied by 1.56 is approximately 19.03.
What is tenth of a decimal?
It is a decimal number whose magnitude is one tenth as large.
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.
