Jane wants to buy a barbecue.
She sees this offer.
Barbecue £150
Pay 20% deposit.
(a) Work out 20% of £150 for Jane.

Answer 1

answer: 150 ( 20 / 100 ) = £30

20% can also be written as 20 / 100 as percent means ‘per hundred.’ just multiply that with your number !

alternatively

10% = 150 / 10 = 15

20% = 15 * 2 = £30
