When multiplying two factors each one with a decimal place how many decimal places should the answer have?
You need to add up the number of digits to the right of the decimal to find the number of digits in the answer. If the first factor has 2 digits to the right of the decimal point and the second factor has 3, the final answer will have 5 digits to the right of the decimal point.
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.

Repeating decimal definition?
A repeating decimal is a number expressed in decimal form in which, after a finite number of miscellaneous digits, the number continues with a string of a finite number of digits which repeats itself without end.
What is the definition for terminating decimal?
It is a decimal representation where, after a finite number of digits, all subsequent digits are 0 [or of them all 9].
When multiplying decimals where do you move the decimal?
the answer is it stays in the same place.* * * * *Not quite.Suppose you want to multiply two decimal numbers A and B. Multiply the two numbers ignoring the decimal points.Count the number of digits after the decimal point in the number A.Count the number of digits after the decimal point in the number B.Add these two numbers together. This is the number of digits you want after the decimal point in the answer. So count back from the end.Example:2.54 * 3.5 (this is number of centimetres in 3.5 inches)254*35 = 8890Number of digits after the decimal point in 2.54 is 2 (5 and 4).Number of digits after the decimal point in 3.5 is 1 (5).2 + 1 = 3 so there must be 3 digits after the decimal point in the answer.Therefore 8890 becomes 8.890NOW, you can simplify it to 8.89
