2:2

Do you mean one of these? Here are the common interpretations:

• Ratio: 2:2 simplifies to 1:1 (divide both terms by their gcd, 2).
• Fraction: 2/2 = 1.
• If you meant a score, 2–2 is a draw.

If you’re preparing for an exam, I can show the steps or apply it to a larger problem. Which interpretation did you intend? If you have a specific problem, paste it and I’ll work through it.
