How much does a large milkshake contain?
I divided 300 by 3 to get 100. So for every 1/3 is 100ml. Since a large milkshake is 2/3 more than a small it is 200ml larger (500ml).
I used the same strategy from part A of this question and learned that Mr. Murrin drinks 200ml of milkshake. For Miss Hoyne I multyplied 500ml by 1/2 to get 250ml. Miss Hoyne drank more.
This one was really easy. I multyplied 1/3 by three which got me 3/3 or one whole. If I did this I have to do the same to 1/2 of a can. 1/2 multyplied by 3 equals 1 1/2. 1 1/2 cans is needed to paint the whole room.
