Four divided by 0.8 is equal to what.
00:00:08.530 --> 00:00:14.540
In this question, we’re being asked to divide an integer, four, by a decimal, 0.8.
00:00:16.070 --> 00:00:19.380
To do this, we can first express the division as a fraction.
00:00:19.600 --> 00:00:25.530
Four divided by 0.8 is equal to the fraction four over 0.8.
00:00:27.210 --> 00:00:30.880
Working out how many times 0.8 goes into four is tricky.
00:00:31.150 --> 00:00:33.790
We’d much prefer to be able to divide by an integer.
00:00:34.960 --> 00:00:40.270
What we’re going to do is find an equivalent fraction where the denominator is no longer a decimal.
00:00:41.920 --> 00:00:47.010
If we multiply the denominator of the fraction by 10, then it becomes an integer, eight.
00:00:48.630 --> 00:00:53.510
In order to keep the two fractions equivalent, we need to perform the same operation to the numerator.
00:00:53.670 --> 00:00:56.030
So we also need to multiply four by 10.
00:00:56.570 --> 00:00:58.710
Four multiplied by 10 is 40.
00:01:00.490 --> 00:01:02.790
Remember, these two fractions are equivalent.
00:01:02.950 --> 00:01:10.950
And therefore, four divided by 0.8 is equivalent to working out 40 divided by eight, a much easier calculation.
00:01:12.630 --> 00:01:15.400
40 divided by eight is equal to five.
00:01:17.300 --> 00:01:22.960
As the two fractions are equivalent, there’s no need to do anything further with this answer such as dividing by 10.
00:01:23.490 --> 00:01:27.000
Four divided by 0.8 is equal to five.
