Why does the number of slices present before bob came divided by 3/4 equal the total number of slices in the pizza?

    Why does the number of slices present before bob came divided by 3/4 (how much of the pizza it was) the total number of slices in the pizza? How does that work? Shouldn't you do some more? I don't get it.

    This is because

    and we found that there were 9 slices before Bob ate (based on working backwards from the 3 slices at the end).

    To find the number of slices in the original pizza, divide both sides by 3/4:

    Let me know if you have any more questions!

    But why do you divide?

    You divide because in the original equation in my prior post, the "number of slices in the whole pizza" is multiplied by 3/4:

    We want to solve for the number of slices in the whole pizza, so we want to get the "whole pizza" by itself. That is why we divide by 3/4.

    I hope this helps!
