How many eighths are there in one-half?
00:00:04.990 --> 00:00:09.920
Well, in order to answer this question, we need to divide one-half by one-eighth.
00:00:11.600 --> 00:00:13.780
We will firstly look at this pictorially.
00:00:15.370 --> 00:00:21.850
If we consider the two squares, the first has been split into halves as there are two equal pieces.
00:00:22.550 --> 00:00:27.740
The second square has been split into eighths as there are eight equal pieces.
00:00:29.450 --> 00:00:32.220
How many of the eighths are equal to one-half?
00:00:33.600 --> 00:00:38.230
Well, looking at the second diagram, it is clear that there are four-eighths in one-half.
00:00:39.440 --> 00:00:41.530
Therefore, our answer is four.
00:00:43.440 --> 00:00:48.440
An alternative method would have been to have divided one-half by one-eighth.
00:00:49.780 --> 00:00:57.260
Well, dividing by one-eighth is the same as multiplying by eight as there are eight-eighths in one whole one.
00:00:58.830 --> 00:01:03.700
One-half multiplied by eight or half of eight is equal to four.
00:01:04.300 --> 00:01:08.790
Therefore, once again, we can see that there are four-eighths in one-half.
