Give your answer in its simplest form.

Answer 1

Answer: 1/10 of proportion

Step-by-step explanation:

Let’s say Brain picks 1 cola bottle.

He picks 3 times as many as smarties as coal bottles, so he finally picked 3 of smarties.

Then he picks up twice as many marshmallows as smarties, so he finally picked 2 * 3 = 6 marshmallows

Therefore, the ratio of 3 types of sweets = 1 : 3 : 6

Thus,

The proportion of the bag containing cola bottles is,

= 1/(1+3+6)

= 1/10
