The question "How many eights are in the whole" can be interpreted in different ways depending on what "the whole" refers to. If "the whole" means a single unit or 1, then there are zero eights in it, since 8 is greater than 1. However, if you're asking how many times 8 fits into a larger number, you would divide that number by 8. For example, in 64, there are eight eights.

Eight eights constitute a whole.
In 7 whole ones, there are 0 eights. Since 8 is greater than 7, it cannot be contained within it. Therefore, the answer is zero eights in 7 whole ones.
eight eghts make a whole
There are zero eights in 3 and a half. The number 3.5 is less than 8, so it cannot contain any whole eights.
Eight sevenths of them.
