How you know the number of decimal places that should be in the product when you multiply two decimal numbers together?
Count the number of digits after the decimal point in the first number being multiplied. Count the number of digits after the decimal point in the second number being multiplied. Add the two numbers. This is the number of digits after the decimal point in the answer. But make sure that any trailing 0s are included. To calulate 0.42 * 3.451: 41*3451 = 144942 Digits after point in first number = 2 Digits after point in second number = 3 2 + 3 = 5 So digits after point in answer = 5 So answer = 1.44942 But To calulate 0.42 * 3.45: 42*345 = 14490 <<< it is vital that the last 0 here is kept till the last stage. Digits after point in first number = 2 Digits after point in second number = 2 2 + 2 = 4 So digits after point in answer = 4 So answer = 1.4490 = 1.449
Is a whole number terminating?
A whole number can have (a) no digits after the decimal point - in which case it terminates at the decimal point, or (b) has a non-terminating sequence of 9s immediately after the decimal point.
The number 36.4375 has haw many decimal place?
Well, darling, the number 36.4375 has four decimal places. It's not rocket science, honey, just count those digits after the decimal point. So, in this case, you've got 4 decimal places to work with. Hope that clears things up for you!
Is 6.5 a whole number?
A number that has non-zero digits after the decimal point is NOT a whole number.
The smallest positive two digit number?
0.1 is the smallest positive number with 2 digits and a decimal point. without a decimal point the smallest is 10.
What is a decimal number which ends after a finite number of digits after the decimal point is called?
It is a terminating decimal.
What is the answer to a number with one or more digits to the right of a decimal point is called a?
It is a decimal fraction.
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. 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. 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 ia a number with one or more digits to the right of the decimal point called?
It is a decimal fraction.
Is a decimal number with two digits is sometimes equal to a decimal number with three digits?
Only if the final digit, after the decimal point, is zero.
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
What is a rational number in decimal form that has a finite number of digits after the decimal point?
I think it's a repeating decimal.
Define significant figures?
Significant figures are the digits in a number that convey meaningful information about its precision. They consist of all non-zero digits, zeros between non-zero digits, and trailing zeros after a decimal point or before a written decimal point in a number without an explicit decimal point.

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.
Is -1.15 a whole number?
If it has digits after a decimal point, then it's NOT a whole number.
Where is the increase decimal button?
It increases the number of digits displayed after the decimal point. It will not change the value of the number.
