Which of the following is equal to
47 pounds?

We’re shown four different amounts
of money. We have to count these groups of
money to find out which is equal to 47 pounds. Let’s start by counting the first
group. We’ve ordered the money from the
notes with the greatest value, the 20-pound notes, down to the coin with the least
value, which is the two-pound coin. Now we can count forward on the
number line to find the total amount of money shown.

Let’s start by counting our two
20-pound notes. We need to count forward in 20s:
20, 40. Now we need to count forward 10 to
add our 10-pound note. 10 more than 40 is 50. We need to count forward five from
50 to add our five-pound note. Start at 50, 51, 52, 53, 54,
55. Five more than 50 is 55. We already know that this group of
coins is not equal to 47 pounds, but let’s finish counting. We just need to count forward two
to add the two-pound coin. Two more than 55 is 57. So we know this is not the group
we’re looking for. Let’s write the total amount just
to remind us, 57 pounds.

Is this group of notes and coins
worth 47 pounds? Let’s count to find the total. Again, we’ve got two 20-pound
notes, so we need to count forward by 20 two times: 20, 40. Next, we need to count our three
two-pound coins. So we need to start at 40 and count
forward in twos three times. 42, 44, 46. Again, we’re very close to 47
pounds. We just got one more coin to add,
and it’s a one-pound coin. One more than 46 is 47. This group of coins and notes is
equal to 47 pounds. 20, 40, 42, 44, 46, 47.

This group is equal to 45
pounds. 10, 20, 30, 35, 40, 42, 44, 45. Let’s quickly count how much this
group is worth. 20, 30, 40, 45, 46, 47, 48, 49. These notes and coins are worth 49
pounds. We picked the amount of notes and
coins equal to 47 pounds.
