00:00:01.160 --> 00:00:10.910
Estimate the value of 2.265 divided by 0.52.
00:00:13.420 --> 00:00:20.640
The first thing we can say is that 2.265 is about two.
00:00:22.690 --> 00:00:29.310
Then we can say that 0.52 is about one-half.
00:00:29.670 --> 00:00:33.070
It’s about zero and five-tenths.
00:00:34.470 --> 00:00:37.790
Now we have two divided by five-tenths.
00:00:39.040 --> 00:00:46.110
What if we take this five-tenths and we turned it into a fraction, five-tenths?
00:00:47.610 --> 00:00:53.620
Then we can recognize that five out of ten is the same as one out of two.
00:00:53.770 --> 00:00:54.920
It’s one-half.
00:00:56.180 --> 00:01:00.950
Now we’re asking the question what is two divided by one-half.
00:01:02.370 --> 00:01:11.770
When we’re trying to divide by a fraction, we change the division to multiplication and then we flip the fraction.
00:01:11.990 --> 00:01:15.390
We turn one-half into two over one.
00:01:17.250 --> 00:01:21.110
Now we say two times two over one.
00:01:22.860 --> 00:01:25.590
Two times two equals four.
00:01:27.290 --> 00:01:37.310
The estimate for 2.265 divided by 0.52 would be four.
