Andy, Ben and Charlie share £100 in the ratio 8 : 7 : 5. How much each of them gets?

(I know the answer, please help me understand how I work it out?)

Respuesta :

Answer:

£40, £35, £25

Step-by-step explanation:

Sum the parts of the ratio , 8 + 7 + 5 = 20 parts

Divide the quantity by 20 to find the value of one part of the ratio.

£100 ÷ 20 = £5 ← value of 1 part of the ratio

Andy = 8 × £5 = £40

Ben = 7 × £5 = £35

Charlie = 5 × £5 = £25
