I'm not sure if this is it but wouldn't it be something like a whole barrel of bad apples ruins one good apple. Again I'm not sure. It is a metaphor one bad person can make a whole group bad so an opposite might be
One good person can make a whole group better
coral the barrell
the opposite of whole is a half
the whole entire ruins
release of ethylene gas, a plant hormone for ripening
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" . . .
They are a pair of opposite whole numbers. Except in the case of 0 whose additive opposite is itself and which does not have a mulitplicative opposite.
Mold spores spread to sound food rapidly. Thus we have the old and wise saying, " One rotten apple spoils the whole barrel."
Depends on how big the whole apple was.
Apart from zero (which is its own opposite), the opposites of whole numbers are also whole numbers. You have the set of whole numbers which is also known as the set of integers.
