Answer:
Some choices might be...
5:2
10:4
30:12
275:110 (probably not this one but I put it to prove my point)
Explanation:
To figure out the other options you can multiply both sides by the same number. So 5x4 = 20 and 2x4 = 8 so the ratio could be 20:8
It can be ANY number at all as long as it's rational.
Hope that helps and have a great day!
