we're talking about the rest of the pie.

So, whereas this is one quarter, this in red is three quarters. Okay?

We can also talk about "a fifth", so, if the pie has five parts, 20% would be a fifth.

Okay? So, in red is a fifth, or we can also talk about "a sixth".

If we have one, two, three, four, five, six, six slices, six equal slices, if I color in one of these, that becomes a sixth.

Now, one thing to note: when we talked about "half", we don't use an article, we don't say: "a half". Okay?

Notice there is no "a" here, when we talk about "a third", "a quarter", "a sixth", "a fifth" - we do have "a" there. Okay?

So, you don't need "a" with "half", but you do need it if you're talking about "a third", "a quarter", "a fifth", or "a sixth".

Okay, excellent. So, now let's talk a little more about percents.

Okay, so I made a little bit of a mistake in one of my drawings, a fifth,

I think I drew actually just four slices, here, there's one, two, three, four, five.

So, if I colored in one of these, this slice would be a fifth. Okay?

So, now what we're going to do is we're going to talk about another way to boost your vocabulary mark when you're talking about numbers and pie charts.

So, I have here a new pie chart.
