Dialogue: 0,0:00:00.61,0:00:06.15,Default,,0000,0000,0000,,A baby's T-shirt requires 4/5\Nyards of fabric, or 4/5 of a
Dialogue: 0,0:00:06.15,0:00:07.47,Default,,0000,0000,0000,,yard of fabric.
Dialogue: 0,0:00:07.47,0:00:11.19,Default,,0000,0000,0000,,How many T-shirts can be\Nmade from 48 yards?
Dialogue: 0,0:00:11.19,0:00:13.25,Default,,0000,0000,0000,,So what we want to do is we\Nessentially want to say how
Dialogue: 0,0:00:13.25,0:00:18.43,Default,,0000,0000,0000,,many groups of 4/5 of a yard\Ncan we make with 48 yards?
Dialogue: 0,0:00:18.43,0:00:24.68,Default,,0000,0000,0000,,So you literally view this as\Nwe want to take 48 yards and
Dialogue: 0,0:00:24.68,0:00:29.81,Default,,0000,0000,0000,,divide it into groups of 4/5\Nof a yard, and say how many
Dialogue: 0,0:00:29.81,0:00:30.61,Default,,0000,0000,0000,,groups are there?
Dialogue: 0,0:00:30.61,0:00:32.43,Default,,0000,0000,0000,,Because each of those\Ngroups can make
Dialogue: 0,0:00:32.43,0:00:33.74,Default,,0000,0000,0000,,one to baby's T-shirt.
Dialogue: 0,0:00:33.74,0:00:37.11,Default,,0000,0000,0000,,If you give me 4/5 of a yard,\None baby's T-shirt, so the
Dialogue: 0,0:00:37.11,0:00:40.72,Default,,0000,0000,0000,,number of groups of 4/5 is the\Nnumber of babies' T-shirts.
Dialogue: 0,0:00:40.72,0:00:43.34,Default,,0000,0000,0000,,Now, when we divide by a\Nfraction, we just have to
Dialogue: 0,0:00:43.34,0:00:45.97,Default,,0000,0000,0000,,remember that that is the same\Nthing, that is completely
Dialogue: 0,0:00:45.97,0:00:51.03,Default,,0000,0000,0000,,equivalent to multiplying\Ntimes the
Dialogue: 0,0:00:51.03,0:00:52.36,Default,,0000,0000,0000,,reciprocal of the fraction.
Dialogue: 0,0:00:52.36,0:00:56.70,Default,,0000,0000,0000,,So if we have 4/5 here,\Nthat'll be 5/4, the
Dialogue: 0,0:00:56.70,0:00:57.66,Default,,0000,0000,0000,,reciprocal.
Dialogue: 0,0:00:57.66,0:00:59.96,Default,,0000,0000,0000,,Now, you still might say, hey, I\Nhave a whole number here and
Dialogue: 0,0:00:59.96,0:01:02.47,Default,,0000,0000,0000,,a fraction, and you just have\Nto remember any whole number
Dialogue: 0,0:01:02.47,0:01:04.10,Default,,0000,0000,0000,,can be written as a fraction.
Dialogue: 0,0:01:04.10,0:01:11.34,Default,,0000,0000,0000,,This is the same thing\Nas 48/1 times 5/4.
Dialogue: 0,0:01:11.34,0:01:14.04,Default,,0000,0000,0000,,Now, we could just multiply it\Nout at this point and figure
Dialogue: 0,0:01:14.04,0:01:19.38,Default,,0000,0000,0000,,out what 48 times 5 is and\Nthat'll be over 4, but that'll
Dialogue: 0,0:01:19.38,0:01:21.65,Default,,0000,0000,0000,,get big numbers and it'll be\Nhard to kind of divide and all
Dialogue: 0,0:01:21.65,0:01:23.70,Default,,0000,0000,0000,,that, but we could divide at\Nthis stage right here.
Dialogue: 0,0:01:23.70,0:01:26.23,Default,,0000,0000,0000,,We could divide the numerator\Nand the denominator by 4.
Dialogue: 0,0:01:26.23,0:01:30.24,Default,,0000,0000,0000,,Or we could say, look, this is\Ngoing to be equal to 48 times
Dialogue: 0,0:01:30.24,0:01:34.07,Default,,0000,0000,0000,,5, whatever that is, over 4.
Dialogue: 0,0:01:34.07,0:01:36.37,Default,,0000,0000,0000,,Now, let's divide the\Nnumerator by 4.
Dialogue: 0,0:01:36.37,0:01:40.50,Default,,0000,0000,0000,,Well, we could divide 48 by 4,\Nand we will get to 12, and
Dialogue: 0,0:01:40.50,0:01:42.09,Default,,0000,0000,0000,,whatever we did to the\Nnumerator, we have to do to
Dialogue: 0,0:01:42.09,0:01:45.75,Default,,0000,0000,0000,,the denominator, so if we\Ndivide 4 by 4, we get 1.
Dialogue: 0,0:01:45.75,0:01:51.09,Default,,0000,0000,0000,,So then we're left with 12 times\N5, which is equal to 60.
Dialogue: 0,0:01:51.09,0:01:56.82,Default,,0000,0000,0000,,12 times 5, which is equal to\N60/1, which is the exact same
Dialogue: 0,0:01:56.82,0:01:58.54,Default,,0000,0000,0000,,thing as 60.
Dialogue: 0,0:01:58.54,0:02:02.96,Default,,0000,0000,0000,,So you can actually make 60\Nchildren's or babies' T-shirts
Dialogue: 0,0:02:02.96,0:02:07.30,Default,,0000,0000,0000,,from 48 yards if each of\Nthem use 4/5 of a yard.
