Kayeigh and Rachel each buy clothes in the sale. kayleigh's clothes normally cost £50 but had £5 off. Rachel's clothes normally cost £20 but had £3 off. Who's clothes had the biggest percentage discount

(5/50) x 100 = 10%

(3/20) x 100 = 15%

So Rachel has the biggest discount

Kaleighs clothes:

£50=100%

so to find one percent you divide by 100

£0.5=1%

if you then do how much of (£5) by one percent which is (£0.5)

then you get

5 divided by 0.5 to get 10

which means kaleighs clothes are 10% off

mimick this idea for Rachels clothes and the greater the percentage, shows whos clothes had the biggest percentage discount
