If Mary and Bob share £60 in the ratio 5:7. Work out how much each person gets. Show working out ...

I'm not entirely sure if this is the right way of doing it)

So you add the two numbers in the ratio (5 and 7) which makes 12 and you divide £60 by that number

60 divided by 12 is 5 so you times that by 5 to get Mary's value (£25) and by 7 to get Bob's (£35)

You can check this by adding the 2 numbers and if it adds up to £60, you're probably right

Total ratio: 5+7=12

£60:12 = £5

Mary: 5 * £5 = £25

Bob: 7 * £5 = £ 35
