By the time students of KS2 Maths reach Year Six they should be quite confident when solving problems to do with money. They should know whether to use addition, subtraction, multiplication or division to solve different problems such as working out change, finding how much something will cost, percentages of amounts or converting between currencies. They will now be set problems involving higher amounts of money.

Solving money problems will include division, multiplication, addition and subtraction. Addition is used to find how much more than one item will cost. Subtraction will tell you how much change you should get. Division and multiplication could tell you how long you would have to save up to buy something or how much pocket money you would get over a year.

Do you know how much you'd save if there was a 20% off sale? How long would you need to save £1.50 each week to get £10? Play this quiz to find out how good you are at solving money problems.

1.

There is 10% discount off a table usually costing £240. How much is the table after the discount?

£24

£216

£220

£230

To calculate 10% divide by 10

2.

Peter has saved £23.78. He spends £15.29. How much does he have left?

£7.39

£7.49

£8.39

£8.49

To do this you could take away first the pence units, then pence tens, then pound units then pound tens:

£23.78 - 9p = £23.69

£23.69 - 20p = £23.49

£23.49 - £5 = £18.49

£18.49 - £10 = £8.49

£23.78 - 9p = £23.69

£23.69 - 20p = £23.49

£23.49 - £5 = £18.49

£18.49 - £10 = £8.49

3.

What is the total of £210, £15, £5.65 and £1.25?

£230.90

£231.00

£231.50

£231.90

One way to work this out is to add the pence first: 65p + 25p = 90p

Next add the units of pounds: £0 + £5 + £5 + £1 = £11

Then add the tens of pounds: £10 + £10 = £20

Then add all of these to the hundreds of pounds: £200 + £20 + £11 + 90p = £231.90

Next add the units of pounds: £0 + £5 + £5 + £1 = £11

Then add the tens of pounds: £10 + £10 = £20

Then add all of these to the hundreds of pounds: £200 + £20 + £11 + 90p = £231.90

4.

A coat costs £36 in a half price sale. How much did the coat cost before the sale?

£18

£45

£54

£72

36 x 2 = 72 so the coat must have cost £72 before the sale

5.

There are 1.18 Euros to £1. A car costs 11,800 Euro. How much is the car in pounds?

£100

£1,000

£10,000

£100,000

To calculate divide 11,800 by 1.18

6.

The total cost of 10 burgers is £16. How much does one burger cost?

16p

£1.50

£1.60

£2

To divide £16 by 10 just move the decimal point one place to the left:

£16.00 ÷ 10 = £1.60

£16.00 ÷ 10 = £1.60

7.

Ali bought some cheese for £3.76, a chicken for £5.30 and a pan for £16. How much change did he have from £50?

£24.94

£25.00

£25.06

£25.94

£3.76 + £5.30 + £16 = £25.06 which is £4.94 less than £30. £30 is £20 less than £50

8.

A cinema ticket costs £3.60 and a bucket of popcorn is £2.50. Five children went to the cinema and shared 3 buckets of popcorn. How much did they spend altogether?

£25.00

£25.50

£35.00

£35.50

To express this as a number sentence would be (3.60 x 5) + (2.50 x 3)

9.

An estate agent’s fee for selling a house is 10%. How much is the fee for a house sold for £75,000?

£7.50

£75

£750

£7,500

Remember that 10% is the same as one tenth

10.

What is the cost of 15 balloons at 23p each?

£2.30

£3.45

£4.45

£4.55

To work out 15 x 23 you could work out 10 x 23 and 5 x 23 and add the two together:

10 x 23p = £2.30 and 5 x 23p = £1.15

£2.30 + £1.15 = £3.45

10 x 23p = £2.30 and 5 x 23p = £1.15

£2.30 + £1.15 = £3.45
