0:00:00.580,0:00:06.610
Let's see if we can write[br]1.501 as a percentage.

0:00:06.610,0:00:09.030
Now we really just want[br]to write this quantity

0:00:09.030,0:00:11.050
as something over 100.

0:00:11.050,0:00:12.880
So what we can do is[br]we can say that this

0:00:12.880,0:00:16.480
is the same thing[br]as 1.501 over 1.

0:00:16.480,0:00:17.940
We haven't changed its value.

0:00:17.940,0:00:22.504
And let's multiply[br]it times 100/100.

0:00:22.504,0:00:24.920
When we do this product-- and[br]I haven't changed the value.

0:00:24.920,0:00:26.770
This is just multiplying[br]something times 1.

0:00:26.770,0:00:28.770
But when we do it, we're[br]going to change the way

0:00:28.770,0:00:29.895
that we're representing it.

0:00:29.895,0:00:33.570
The denominator now is[br]going to be 1 times 100.

0:00:33.570,0:00:35.000
So that's pretty[br]straightforward.

0:00:35.000,0:00:36.980
That's just going to be 100.

0:00:36.980,0:00:38.740
And then the[br]numerator, we're going

0:00:38.740,0:00:42.730
to want to multiply[br]1.501 times 100.

0:00:42.730,0:00:45.460
And so if we multiply[br]this times 10,

0:00:45.460,0:00:47.250
we would move the[br]decimal one over.

0:00:47.250,0:00:48.750
We want to multiply[br]it by 100, so we

0:00:48.750,0:00:50.600
want to multiply by 10 again.

0:00:50.600,0:00:52.970
So we're going to move the[br]decimal over to the right

0:00:52.970,0:00:53.470
twice.

0:00:53.470,0:00:56.000
We're multiplying[br]it by 10 twice,

0:00:56.000,0:00:57.907
or you're multiplying it by 100.

0:00:57.907,0:00:58.990
This is multiplying by 10.

0:00:58.990,0:01:00.310
This is multiplying by 100.

0:01:00.310,0:01:02.310
So this is where the[br]decimal's going to sit now.

0:01:02.310,0:01:07.060
So we're going to get 150.1.

0:01:07.060,0:01:12.340
And so we've rewritten the[br]1.501 as 150.1 over 100,

0:01:12.340,0:01:14.731
or 150.1 per 100.

0:01:14.731,0:01:15.480
Let me write that.

0:01:15.480,0:01:22.530
150.1 per 100, which[br]is the same thing

0:01:22.530,0:01:32.980
as 150.1 per cent, which is[br]the same thing as 150.1%.

0:01:32.980,0:01:33.687
And we're done.

0:01:33.687,0:01:35.770
And, essentially, all[br]you're doing-- if you really

0:01:35.770,0:01:38.740
want to simplify the process--[br]we're multiplying this

0:01:38.740,0:01:41.380
by 100 to get 150.1.

0:01:41.380,0:01:43.575
And then we're saying,[br]that is the percentage.

0:01:43.575,0:01:45.950
So you want to make sure that[br]you write the percent there

0:01:45.950,0:01:48.150
or the percent symbol.
