Best Answer

If the number is before the decimal, it is a whole number. The numbers after the decimal represent fractions of whole numbers. For example if you had to work 8.5 hours, you would work 8 whole hours plus one half hour.

An infinite amount of numbers can theoretically be placed after the decimal point.

It depends on where the decimal point is to be placed? For instance, if 1010100 is a whole number, then it would be: 1010100.00 If this is not the case, then more information is needed.

Decimal point

If there is a decimal placed somewhere within the number, such as .3568 could be rounded to .357

Where the decimal is placed you just have to bring it straight down.

When a mixed number (a whole number and a fraction) is written as a decimal, the decimal point divides the whole number and the fractional part. 12 and 75/100 = 12.75 a dot placed after the figure representing units in a decimal fraction.

Yes, decimal is a noun, a singular, common noun. Example sentence: The decimal for hundredths is placed two digits from the right of a number.

Not really.If you are competent in using the basic operations of arithmetic (+ - * /) and follow the riles as these apply to decimal numbers then the decimal point will be correctly placed and finding a whole number estimate will only mean additional calculations which serve no purpose. On the other hand, if you are not that competent then how can you be sure that the whole number estimate that you find is accurate?

As many as you can write.

Like the metric system, the decimal is placed by 10ths. One number away from the decimal point is one-tenth. The second number away is the one-hundredth place. So, basically, it's two numbers away (to the right) of the decimal point.
