2:2

Do you mean the ratio 2:2?

• If so, it simplifies to 1:1 (divide both numbers by their gcd, which is 2).

If you’re using 2:2 in a proportion, e.g., 2:2 = a:b, then a/b = 1, so a = b.

If you’d like, tell me the exact context or give another example and I’ll tailor the explanation. Here are quick related exercises:

• Simplify 6:9 → 2:3
• Solve a proportion: 2:2 = x:y → x = y
• Simplify 0:5 → 0:1 (since 0/5 = 0)
