00:00:03.000 --> 00:00:10.400
Mr Ethan’s car has an average mileage of 22.66 miles per gallon.
00:00:11.380 --> 00:00:15.560
Express this amount as a mixed number in its simplest form.
00:00:17.270 --> 00:00:25.150
We’re told that, on average, Mr Ethan’s car travels 22.66 miles per gallon.
00:00:26.640 --> 00:00:31.500
And we’re asked to express this amount as a mixed number.
00:00:32.970 --> 00:00:37.620
A mixed number contains a whole number and a fraction.
00:00:39.080 --> 00:00:48.310
At the moment, our number 22.66 has a whole part, which is 22, and a decimal part.
00:00:48.530 --> 00:00:52.660
66 is worth sixty-six hundredths.
00:00:55.400 --> 00:01:02.180
We could write 0.66 as a decimal fraction, sixty-six hundredths.
00:01:04.830 --> 00:01:11.600
So, 22.66 is equal to 22 and sixty-six hundredths.
00:01:13.250 --> 00:01:17.590
22 and sixty-six hundredths is now a mixed number.
00:01:19.000 --> 00:01:23.350
But we have to express the mixed number in its simplest form.
00:01:23.980 --> 00:01:27.750
Now, can we simplify sixty-six hundredths?
00:01:29.180 --> 00:01:34.460
What can we divide 66 and 100 by to simplify the fraction?
00:01:35.930 --> 00:01:38.400
We can divide both numbers by two.
00:01:39.200 --> 00:01:43.550
66 divided by two is 33.
00:01:45.230 --> 00:01:48.620
And 100 divided by two is 50.
00:01:50.680 --> 00:01:59.090
22 and sixty-six hundredths in its simplest form is 22 and thirty-three fiftieths.
00:02:00.690 --> 00:02:06.220
Mr Ethan’s car has an average mileage of 22.66 miles per gallon.
00:02:07.570 --> 00:02:17.730
This amount, expressed as a mixed number in its simplest form, is 22 and thirty-three fiftieths miles per gallon.
