2:2

If you meant the ratio 2:2, it simplifies to 1:1 (divide both numbers by their gcd, 2). Also, 2:2 is the same as the fraction 2/2 = 1.

Quick notes:

• Method: find gcd(a,b) and divide both by gcd(a,b).
• Examples:
  • 6:8 → gcd 2 → 3:4
  • 9:3 → gcd 3 → 3:1
  • 0:5 → gcd 5 → 0:1

If you had a different context (a proportion, a statistical ratio, etc.), tell me and I’ll tailor the explanation.
