0:00:00.590,0:00:04.725
We're asked to identify the[br]numerator and denominator in

0:00:04.725,0:00:08.400
the fraction 3 over 4, or 3/4.

0:00:08.400,0:00:11.140
So let's rewrite this just[br]so it's nice and big.

0:00:11.140,0:00:12.580
So let me just write[br]the fraction.

0:00:12.580,0:00:20.470
So we have 3 over 4, 3/4.

0:00:20.470,0:00:22.880
Now, they want us to identify[br]the numerator and the

0:00:22.880,0:00:24.130
denominator.

0:00:25.950,0:00:29.040
So the numerator is just the[br]number on top, so the

0:00:29.040,0:00:31.600
numerator is the[br]3 right there.

0:00:31.600,0:00:34.080
And then they want us to[br]find the denominator.

0:00:34.080,0:00:37.160
The denominator is just the[br]number on the bottom.

0:00:37.160,0:00:38.050
It's the 4.

0:00:38.050,0:00:39.180
So if they say what's[br]the numerator?

0:00:39.180,0:00:39.810
3.

0:00:39.810,0:00:41.310
What's the denominator?

0:00:41.310,0:00:43.220
It's 4, just the number[br]on the bottom.

0:00:43.220,0:00:44.910
They could've just called this[br]the number on the bottom.

0:00:44.910,0:00:47.340
They could've just called[br]this the number on top.

0:00:47.340,0:00:49.680
Now to think about what this[br]represents, what this fraction

0:00:49.680,0:00:52.600
represents, you can think[br]of it as three out of

0:00:52.600,0:00:54.270
four pieces of a pie.

0:00:54.270,0:00:55.380
That's how I think about it.

0:00:55.380,0:00:58.330
So you can imagine, the[br]denominator tells us, what are

0:00:58.330,0:01:01.680
we taking a fraction out of or[br]how many pieces are there?

0:01:01.680,0:01:03.950
So let's imagine a[br]pie like this.

0:01:03.950,0:01:07.240
So we could draw like[br]a square pie.

0:01:11.250,0:01:13.230
So this is what the denominator[br]represents.

0:01:13.230,0:01:17.100
This is what the number on[br]the bottom represents.

0:01:17.100,0:01:20.510
And then 3 says, we are[br]representing three of those

0:01:20.510,0:01:21.950
four pieces.

0:01:21.950,0:01:25.390
So this 3 tells us that out of[br]4 possible ones, I guess you

0:01:25.390,0:01:28.580
could think of it, we are using[br]three, or maybe we're

0:01:28.580,0:01:30.360
eating three.

0:01:30.360,0:01:33.205
So you can imagine if someone[br]says I ate three-fourths of a

0:01:33.205,0:01:35.880
pie-- this would be read as[br]three-fourths-- they're eating

0:01:35.880,0:01:38.740
the blue portion of the pie[br]if we cut it this way.

0:01:38.740,0:01:42.380
If we imagine a round pie,[br]it would look like this.

0:01:42.380,0:01:43.905
Let me draw a round pie.

0:01:43.905,0:01:47.190
So that is my round pie.

0:01:47.190,0:01:50.400
Let me cut it into four[br]equal pieces or

0:01:50.400,0:01:52.320
roughly equal pieces.

0:01:52.320,0:01:58.030
And if someone says I ate[br]three-fourths of this pie,

0:01:58.030,0:02:01.070
where the 3 is the numerator,[br]and then the 4, and you'd read

0:02:01.070,0:02:04.650
that as three-fourths, the 4 is[br]the denominator, they would

0:02:04.650,0:02:06.190
eat this much of the pie.

0:02:06.190,0:02:08.480
They would eat 3 of[br]the 4 pieces.

0:02:12.910,0:02:19.520
So this is is one piece, this[br]is two pieces, and this is

0:02:19.520,0:02:20.720
three pieces.

0:02:20.720,0:02:23.200
So you could imagine the 4, the[br]denominator represents the

0:02:23.200,0:02:27.730
total number of pieces in the[br]pie, and then the 3 represents

0:02:27.730,0:02:30.200
how many of those we ate.
