Why is the opposite of a decimal a whole?
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.
