vichka [17]

Answer:

Yes 4:3

Step-by-step explanation:

To solve this, take the the inside number and subtract in from the outside number. Look at the question very carefully for this part...

Since it says the ratio of the outside number to the inside number, take that number and see how many times it can fit into the outside number. In this case, it is 4, and than for the inside number, it is 3.

Now do the same for the other measurement and see if it has the same ratio, and if it does, that is the answer.
