Here is a cool fact about division problems. Let's say you divide 3.6 by 0.9. Then, figure out the answer. Now let's say that we change 3.6 to 0.00036. Then let's say that we change 0.9 to 0.0009. The answer would still be the same, because what you have to do to one side of the equation, you have to do the other, or it won't be equivalent.
