00:00:04.500 --> 00:00:08.860
I took my blocks and built two walls.
00:00:09.360 --> 00:00:14.060
In each wall one block was one fourth of them
all.
00:00:15.380 --> 00:00:19.640
Two divided by one fourth equals eight;
00:00:20.500 --> 00:00:24.960
eight blocks to build the wall at my castle
gate.
00:00:26.540 --> 00:00:30.640
To divide a whole number by a fraction we
start
00:00:32.240 --> 00:00:36.340
by dividing the whole number into fractional
parts.
00:00:37.780 --> 00:00:42.620
Then count the number of fractional parts
present;
00:00:43.760 --> 00:00:47.720
and that will be the quotient.
00:00:48.960 --> 00:00:54.960
Then I took my blocks and built three seats.
00:00:55.200 --> 00:00:59.899
One block was one fifth of each.
00:00:59.899 --> 00:01:04.999
Three divided by one fifth equals fifteen;
00:01:05.000 --> 00:01:10.240
that’s how many blocks it took to build
my seats.
00:01:11.280 --> 00:01:16.160
To divide a whole number by a fraction we
start
00:01:16.580 --> 00:01:21.260
by dividing the whole number into fractional
parts.
00:01:22.220 --> 00:01:27.120
Then count the number of fractional parts
present;
00:01:28.400 --> 00:01:32.880
and that will be the quotient.
00:01:33.920 --> 00:01:36.640
When there’s a fraction we want to divide
by,
00:01:36.670 --> 00:01:38.909
we can flip the fraction and multiply.
00:01:38.909 --> 00:01:41.500
Think of three divided by one fifth:
00:01:41.500 --> 00:01:44.369
we’ll get the same answer if we multiply
and flip.
00:01:44.369 --> 00:01:47.649
So these expressions are equal, and we call
00:01:47.680 --> 00:01:50.560
five over one, one-fifth's reciprocal.
00:01:50.560 --> 00:01:55.760
To divide a whole number by a fraction we
start
00:01:55.760 --> 00:02:01.040
by dividing the whole number into fractional
parts.
00:02:01.360 --> 00:02:07.440
Then count the number of fractional parts
present;
00:02:07.440 --> 00:02:11.700
and that will be the quotient.
