2:2

Since both parts are the same, 2:2 simplifies to 1:1.

• As a fraction: 2/2 = 1
• As a percentage of the total (if the two parts form a whole): each part is 50%

If you meant something else by 2:2 (e.g., a time notation or a proportion in a problem), let me know and I’ll tailor the answer. Want a quick related practice problem?
