Henry gets pic 'n mix when at the cinema and makes his bag up with 3 types of sweet. He picks 3 times as many smarties as cola bottles. He also picks twice as many marshmallows as smarties. What proportion of the bag of sweets are marshmallows? Give your answer in its simplest form.

s =smarties

m= mellows   = 2 * s

c = colas       = 1/3 s

 

total is   s   + 2s  + 1/3 s        mellows are  2s

 

2s/(s+2s+1/3s) = 2s / 10/3 s ) = 6/10 = 3/5   are mellows
