00:00:02.920 --> 00:00:04.280
Amina is shopping.
00:00:05.040 --> 00:00:10.920
She says “I would like to buy one-quarter of a kilogram of cheese.”
00:00:12.560 --> 00:00:16.560
Write one-quarter on the scales as a decimal.
00:00:18.360 --> 00:00:21.600
The cheese costs one pound 35.
00:00:22.920 --> 00:00:25.040
Amina pays with a two-pound coin.
00:00:26.240 --> 00:00:28.640
How much change should Amina get?
00:00:30.840 --> 00:00:35.480
We have to write one-quarter on the scales as a decimal.
00:00:37.560 --> 00:00:41.360
We would write a half as 0.5.
00:00:42.640 --> 00:00:46.200
We would write a quarter as 0.25.
00:00:47.640 --> 00:00:54.200
So Amina’s cheese would weigh 0.25 kilograms on the scales.
00:00:56.280 --> 00:00:58.840
Now, let’s look at the second part of the question.
00:01:00.160 --> 00:01:02.440
The cheese costs one pound 35.
00:01:02.440 --> 00:01:04.880
And Amina pays with a two-pound coin.
00:01:04.880 --> 00:01:07.720
So we have to work out how much change she should get.
00:01:09.080 --> 00:01:14.400
We need to find the difference between one pound 35 and two pounds.
00:01:15.920 --> 00:01:23.920
If we add five to one pound 35, that will take us to the nearest 10, which is one pound 40.
00:01:25.320 --> 00:01:31.160
Then, we can add 60 pence to one pound 40 to give us two pounds.
00:01:32.520 --> 00:01:36.320
So Amina should get 65-pence change.
00:01:37.800 --> 00:01:41.680
Amina bought one-quarter of a kilogram of cheese.
00:01:42.720 --> 00:01:49.680
We worked out that one-quarter of a kilogram would be 0.25 kilograms on the scales.
00:01:50.680 --> 00:01:53.000
We used a number line to help us.
00:01:53.840 --> 00:01:56.680
Amina paid for her cheese with a two-pound coin.
00:01:57.120 --> 00:01:59.440
Her cheese cost one pound 35.
00:01:59.960 --> 00:02:06.320
So we used a number line to find the difference between one pound 35 and two pounds.
00:02:07.200 --> 00:02:10.840
Amina should get 65-pence change.
