2:2

2:2 simplifies to 1:1.

Why: divide both numbers by their greatest common divisor (2). So 2/2 = 1 and 2/2 = 1.

Extras:

• As a single number ratio: 2:2 = 1.
• As a decimal: 2/2 = 1.
• As a percentage of the total: each part is 50% of the total (since total = 4, each part = 2 → 2/4 = 50%).

If you want, I can give more examples or practice problems.
