2:2

2:2 simplifies to 1:1.

Why:

• gcd(2,2) = 2, divide both terms by 2 → 1:1
• As a fraction: 2/2 = 1
• As a decimal: 1.0; as a percentage: 100%

Implications:

• If A:B = 2:2, then A = B.
• If A+B is fixed (say S), then A = B = S/2.

General tip: any ratio of the form a:a always reduces to 1:1.
