00:00:01.634 --> 00:00:06.214
Pick the coins that make four pounds and 27 pence.
00:00:07.354 --> 00:00:10.594
In this question, we’re given two groups of coins.
00:00:11.314 --> 00:00:14.574
And we’re told to pick the coins that make a certain amount of money.
00:00:15.184 --> 00:00:18.104
Now, the amount we’re looking for is made up of two parts.
00:00:18.884 --> 00:00:22.854
Can you see how the first part is made up of this symbol and the number four?
00:00:23.824 --> 00:00:26.904
This is the symbol that we use to represent pounds.
00:00:27.724 --> 00:00:29.874
And some of our coins are worth pounds.
00:00:30.494 --> 00:00:35.734
Then we can also see that the second part contains the number 27 and a letter, p.
00:00:36.274 --> 00:00:38.934
Do you remember what the letter p stands for when we talk about money?
00:00:39.704 --> 00:00:41.574
It stands for an amount of pence.
00:00:42.164 --> 00:00:49.864
So we’re looking for a group of coins that contains both pounds and pence, four pounds and 27 pence.
00:00:50.654 --> 00:00:55.554
And we can find out which group this is by counting the pounds and the pence separately.
00:00:56.404 --> 00:00:58.594
Let’s start by looking at our first group.
00:00:59.274 --> 00:01:02.604
Do you notice anything interesting about the order that the coins have been put in?
00:01:03.374 --> 00:01:09.894
If you can remember what the value of these coins are, you’ll know that they’ve been put in order from largest to smallest.
00:01:10.824 --> 00:01:17.964
Out of all the coins in the group, this coin here has the most value and these three coins on the end have the least value.
00:01:18.774 --> 00:01:24.344
And you know it does help us when we’re counting money to start with the largest and go all the way through to the smallest amounts.
00:01:25.394 --> 00:01:29.094
So to begin with in this first group, let’s see how many pounds we have.
00:01:29.984 --> 00:01:32.474
Which coins have a value in pounds?
00:01:33.304 --> 00:01:36.394
Well, if we look carefully at each of the coins, we can see their value.
00:01:36.394 --> 00:01:37.334
It’s written on them.
00:01:37.614 --> 00:01:40.774
You might recognize what they’re worth as well by their shape and their color.
00:01:41.924 --> 00:01:44.634
First coin has a value of two pounds.
00:01:45.374 --> 00:01:50.554
And then looking carefully at our next three coins, we can see they’re all the same and they all have a value of one pound.
00:01:51.144 --> 00:01:55.954
Now we know that the only coins that are a value of pounds are the two-pound and the one-pound coin.
00:01:56.404 --> 00:02:01.174
And there aren’t any more of these in the group, so we know that we’ve found all the pounds that are there.
00:02:01.794 --> 00:02:07.774
Two plus three ones is the same as two plus three, which is equal to five.
00:02:08.874 --> 00:02:10.674
We have five pounds.
00:02:11.204 --> 00:02:14.694
Now we’re looking for a group of coins that makes four pounds and something.
00:02:15.414 --> 00:02:18.394
So it looks like perhaps straightaway we’ve found the correct answer.
00:02:18.444 --> 00:02:19.974
It must be the second group.
00:02:20.484 --> 00:02:23.034
Let’s count how many pounds we have then in the second group.
00:02:23.504 --> 00:02:26.084
Once again, we can see a two-pound coin to begin with.
00:02:26.644 --> 00:02:29.244
And this time, we only have two one-pound coins.
00:02:29.604 --> 00:02:34.614
And we know that two plus two ones is the same as two plus two, or four.
00:02:35.194 --> 00:02:37.284
Our second group has four pounds.
00:02:38.034 --> 00:02:41.064
Now, hopefully, the rest of the coins add up to 27 pence.
00:02:41.424 --> 00:02:44.514
But before we add them, have another look at the first group.
00:02:44.514 --> 00:02:46.624
What do you notice about the coins that we have left?
00:02:47.464 --> 00:02:54.184
There are two 10-pence coins, two two-pence coins, and three one-penny coins.
00:02:54.994 --> 00:03:04.574
And this is exactly the same as what we have in our second group: two 10-pence coins, two two-pence coins, and three one-penny coins.
00:03:05.234 --> 00:03:14.434
We know that 10 plus 10 equals 20, two twos have a value of four, and three ones are worth three.
00:03:14.564 --> 00:03:19.104
And we know that if we add 20, four, and three together, we get 27.
00:03:19.674 --> 00:03:23.904
And so both groups have a different number of pounds, but they have the same amount of pence.
00:03:24.154 --> 00:03:29.224
We found the correct answer by counting the number of pounds and then the number of pence.
00:03:29.674 --> 00:03:39.724
The correct group is the one that contains four pounds, made up of a two-pound coin and two one-pound coins, and then 27 pence.
