Alex and Ben were given a total of £240 They shared the money in the ratio 5:7
AfilCa [17]

Answer:

Ben received: £140

Step-by-step explanation:

Total amount = £240

Given ratio: 5:7

It means £240 is divided into 12 parts

So 1 part will be equal to:   £240/12

1 part = £20

Now given ratio is:

5:7

Multiplying each share with £20

5*(£20) : 7* (£20)

£100: £140

So according to ratio amounts:

Alex received:  £100

Ben received: £140

I hope it will help you!
