Price times quantity
You learn to multiply a price: first the pounds, then the pence.
How to work it out
- Multiply the whole pounds by the number.
- Multiply the pence by the number.
- Change every 100 pence into 1 pound.
- Put them together.
£6.30
A worked example
3 × £2.10
- Multiply the pounds: 3 × 2 = 6 pounds.
- Multiply the pence: 3 × 10 = 30 pence.
- Add them together: £6.30.
More examples
4 × £1.25
- Multiply the pounds: 4 × 1 = 4 pounds.
- Multiply the pence: 4 × 25 = 100 pence, and that is £1.
- Add them together: £4 + £1 = £5.
3 × £1.45
- Multiply the pounds: 3 × 1 = 3 pounds.
- Multiply the pence: 3 × 45 = 135 pence.
- Make them into pounds: 135 pence is £1.35.
- Add them together: £3 + £1.35 = £4.35.
Watch out
You only multiply the pounds: 3 × £2.10 becomes £6.10.
Multiply both parts by the number: the pounds and the pence.
You leave 135 pence after the decimal point: £3.135.
If it is 100 pence or more, make a pound from it first.
Tips
- In 4 × £1.25, 4 × 25 pence makes exactly one pound.
Why it works
An amount like £2.10 is 2 pounds and 10 pence. You can multiply those two parts separately, and those are easy sums. Then you put them back together.
