JudyAlright, sweetheart. A whole number is any number without a decimal or fraction, like 1, 2, or 5. A decimal, on the other hand, is a number that includes a decimal point, like 3.14 or 7.5. So basically, one is plain and simple, while the other likes to get a little fancy with its point.

How do you change a whole number to a decimal?
You can't change a whole number to a decimal. A decimal and a whole number are both numbers. A decimal is just a number lower than a whole number, or a number in between two whole numbers.
What is the difference between a whole number and a not whole number?
A whole number does not include a fraction or decimal part. For example, 3, 107, -9 and zero are whole numbers. 2.1, -17,4528765 and two-and-a-half are not whole numbers.
What is the difference between adding whole numbers and adding decimals?
The main difference is that with whole numbers the decimal point is "hiding" (after the last digit of each whole number) whereas with decimal numbers it is clearly visible. In both cases the numbers are added with the decimal points aligned - with whole numbers there are no digits after the decimal points so the decimal points are not written, but if they were they would be visible after the last digit of the whole numbers and they would be automatically aligned; with decimal numbers there may be a different number of digits after each decimal point so it is up to the person doing the arithmetic to ensure the decimal points are aligned.
Is 0.9812 a whole number?
No. It is a decimal value. It lies between the whole numbers 0 and 1. There are no integers between those two, thus 0.9812 is not a whole number.
Where are the integers on a number line?
If you have drawn a number line counting in whole numbers, the integers are those whole number points. Any decimal numbers in between are not integers.
