Answer:
3:5
Step-by-step explanation:
Im going to assume for the last one you mean oranges to apples, which is 5:3
To get the ratio of apples to oranges you must understand how many there are of each, meaning there are 3 apples and 5 oranges.
Then you put it as a ratio
Apples:Oranges
3:5
You do the same for the second question, if my assumption is correct.
Oranges:Apples
5:3
