Daniel is trying to count the money he has. I have 10 pounds and 52 pence. Is Daniel correct?

In the picture, we can see the group of coins that Daniel’s got. And did you notice the way that Daniel describes his coins is by using two units of measurement? This symbol represents the number of pounds that there are. And Daniel says that he has 10 pounds. And we can also see the letter p, which stands for pence. So Daniel has 10 pounds and 52 pence, or does he? Because we’re asked, is he correct?

The only way to find out the answer is for us to count the coins for ourselves. Let’s start by adding up the number of pounds that he has. Which coins can we find that have a value in pounds? Well, it’s quite small on this video, but if we look really closely we can see the words “two pounds” on this particular coin. We know that it’s a two-pound coin because it’s circular. And the color of the coin is silver in the middle with a sort of gold color around the outside.

And there’s another type of coin that has these colors. But this one’s a bit smaller. And it’s not a circle. It has sort of rounded edges to it. And this is a one-pound coin. And again, if we look really closely, we can see the words “one pound” on this coin. So in Daniel’s pile of coins, we can see some are worth two pounds and some are worth one pound.

Let’s begin by counting the pounds then. To begin with, there are four two-pound coins. So these have a value of two, four, six, eight pounds. And then we need to add our three one-pound coins. So if we start from eight, that’s nine, 10, 11. The number of pounds that Daniel has is 11 pounds. And we can see that he tells us he thinks that he has 10 pounds and 52 pence. So it looks like Daniel’s wrong, doesn’t it? Let’s count the number of pence just to finish off.

The remaining coins are a 50-pence coin and then these two coins here, which we know are worth two pence each. So if you start with the coin with the largest value, that’s 50, and then add two twos, that takes us to 52 and then 54. The number of pence that Daniel has is 54 pence. Instead of 10 pounds and 52 pence, Daniel has 11 pounds and 54 pence. We counted the pounds and the pence separately to find our answer. Is Daniel correct? No, he’s not.
