Answer:  Polly = £30 , Andy = £60 , Phoebe = £180

Explanation:

Polly = x
Andy = 2x
Phoebe = 3(2x) = 6x

x + 2x + 6x = £270
9x = £270
x = £30

Polly = x = £30
Andy = 2x  = £60
Phoebe =  6x = £180
Phoebe : Andy : Polly
     6       :   2     :    1

9 parts = £270
1 part = £270 ÷ 9 = £30

Polly = 1 part = £30
Andy = 2 parts =  £30 x 2 =  £60
Phoebe = 6 parts =  £30 x 6 =  £180

Answer: Polly =  £30 Andy =  £60 Phoebe = £180
