Let the projected number of work hours be w.
Then the number of hours he actually worked was 1.25w. This represents the number of hours that Bob actually spent on the project.
Another way in which to answer this would be as follows:
Actual work hours = w + h (h hours beyond the projected w work hours).
This w + h is equivalent to 1.25w. This means that h = 0.25w.
Answer:
First, remember that mathematics is a logical construct.
So, when something has no logical sense, it is undefined.
Now, let's think about a division by zero:
If you have $100, and you want to divide it between 0 people, how much gets each one of them?.
Naturally, there is no logical answer to this question, we can not know how much gets each one of these people because we have no people to divide that money.
Now, we can find another logical problem if we assume that the division is actually defined.
For example if 1 divided by zero is equal to a number A, we have:
1/0 = A
ok, if now multiply both sides by zero we get:
(1/0)*0 = A*0
1*(0/0) = A*0
1 = 0
So, 1/0 can be defined only if 1 = 0, again, a logical problem.
This is why the division by zero is not defined.
