Lets say that the circle above is an apple pie. The apple pie has 10 slices, or parts. If no one takes a piece of the pie then we have all 10 slices of the pie. Since we have all ten slices of pie we can say that we have "10 of the 10 slices" or

...or a full pie (this is sweet potato pie):

Okay, now lets say that 9 people enter the room and they all take a slice of the pie. That means there is only on piece of pie left

We know this because

There's an underlying tend here, which looks like this:

This exact same trend exists for negative fractions we just have to put a negative sign in front of the decimal. This means that:
