CXL
140 in Roman numerals is CXL.

Roman numerals use seven basic symbols: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1,000. The general rule is: reading left to right, values in descending order add up. When a smaller symbol comes before a larger one, it subtracts (e.g., IV = 4), which happens in this case.

Step-by-step conversion of 140:

1. C = 100 → represents hundreds.

2. XL = 50 - 10 = 40 → subtraction rule used.

So, 100 + 40 = 140, or CXL in Roman numeral form.
