Answer:
There isn't a graph or more information to use to find the ratio but I'll put here 3 ways to write a ratio so hopefully that might help. If more information is added later I will edit the answer.
Explanation:
First way:
Use the word "to". For example: 2 to 4.
Second way:
Use a fraction. For example: 2/4.
Third way:
Use a colon. For example: 2:3.
