Best Answer

The question is based on a false premise: the opposite of a decimal is not a whole.

A decimal is simply a way of representing a number is such a way that the place value of each digit is ten times that of the digit to its right. Therefore 4 is a decimal, 2.75 is a decimal.

There are different ways of defining opposite. The additive opposites of the two numbers are -4 and -2.75 so one of them is a whole number, the other is not.

The multiplicative opposites are 0.25 and 0.3636... so neither of them are whole.

the opposite of whole is a half

The difference is that all whole numbers are decimal numbers, but not all decimal numbers are whole numbers. For example a whole number such as 1 is a decimal number but a decimal number such as 1.5 is not a whole number.

Whole numbers are a proper subset of decimal numbers. All whole numbers are decimal numbers but not all decimal numbers are whole numbers.

No. A whole number is a number with no fractional (decimal) part. Therefore a decimal number can not be a whole number. Another view: 35.0 is a whole number AND a decimal. The fact that a number is a decimal does not automatically require it to have a fractional part. Even 35 is a decimal number (without a decimal point).

I'm not sure what a whole decimal is. You could round to a whole number (489334209) or a decimal (489334209.0)

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.

if the opposite you are saying is the inverse, then the answer is no.

What exactly do you mean when you say "the opposite of a whole number" . . .

a decimal is part of a whole number e.g. 0.5 is half a whole numbera whole number is just a normal number e.g. 1, 2, 5, 8, 14, 56 etc. A whole number is on the left side of the dot and the decimal is on the right.Example: whole number decimal decimal number 43 . 684

To the left of a decimal point are whole numbers. On the right of a decimal point are parts of a whole number.
