If £1 = €1.2, then £500 = 500 × 1.2 = €600

A 50% discount means that the price or cost of something is reduced by 50%. Since 50% is the same as one half, the 'Frosty' fridge will sell for £548 ÷ 2 = £274. Per cent means per hundred, so 50% = 50?100 = 1?2 after reducing the fraction to its simplest form by dividing the numerator and denominator by 50

Per cent means per hundred, so 2% = 2?100 = 1?50 after reducing the fraction to its simplest form by dividing the numerator and denominator by 2 ? Interest = 1?50 × £3,500 = £70. Note: '2% of' means that you multiply the 2% with something else: in this case the £3,500. The same applies for other percentages

£50 - £12.19 = £37.81 = what she paid for the three items ? 1 item cost £37.81 ÷ 3 = £12.60 (to the nearest penny)

If £1 = €1.2, then €1,200 = 1,200 ÷ 1.2 = £1,000. You have to divide 1,200 by 1.2 because you want to find out how many 'lots' of 1.2 there are in 1,200: each 'lot' equals £1: this is the same as adding 'lots' of 1.2 to itself until you get to 1,200
|
If £1 = $1.6, then £2,500 = 2,500 × 1.6 = $4,000

Per cent means per hundred, so 1% = 1?100 and 1% of £250 means that you have to multiply 1% with 250: 1?100 × £250 = £2.50
|
Per cent means per hundred, so 75% = 75?100 = 3?4 and 75% of £125,000 means that you have to multiply 75% with £125,000: 3?4 × £125,000 = £93,750

Profit = Selling Price - Cost Price = £5 - £1 = £4. The shop has made a profit of £4. Now £4 as a percentage of £1 = 4?1 × 100% = 400%. Yes! Don't fall into the trap of thinking that if you sell it at four times its cost that you will make a 400% profit: you have to subtract the original cost from your selling price before you can call it profit

Per cent means per hundred, so 10% = 10?100 = 1?10 and 10% of £14,560 means that you have to multiply 10% with £14,560: 1?10 × £14,560 = £1,456. So she will lose £1,456 from her salary: £:14,560 - £1,456 = £13,104
