1) 2:5 ratio
This is a fairly simple process, you count how many of each and then put them in order the way the question asks.
So there are 5 cans and 2 bottles. The question asks "bottles to cans" so the correct answer HAS to be 2:5, NOT 5:2.
2) 3:1
There is 1 spoon and 3 forks. The question asks "forks to spoons" so the correct answer HAS to be 3:1, NOT 1:3
