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

2/3

Explanation: Assume that the number of smarties he picked is c.

Now, we are given that:

1- He picked 3 times as many cola bottles as smarties. This means that:

Number of cola bottles he picked = 3s

2- He picked twice as many smarties as marshmallows. This means that:

number of marshmallows he picked = 0.5s

Now to get the proportion o f cola bottles, we will divide the number of cola bottles by the total number of sweets as follows:

proportion of cola bottles =  

Hope this helps :)

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
