LXXVII
77 in Roman numerals is LXXVII.

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 does not happen in this case.

Step-by-step conversion of 77:

1. L = 50 → represents tens.

2. XX = 10 + 10 = 20 → X repeated 2 times.

3. V = 5 → represents units.

4. II = 1 + 1 = 2 → I repeated 2 times.

So, 50 + 20 + 5 + 2 = 77, or LXXVII in Roman numeral form.

  • Add the values of the numerals when a smaller numeral follows a larger one (XI = 11)
  • Subtract the smaller of the two numerals from the larger one when a smaller numeral precedes a larger one (IV = 4)
  • Only I, X, and C may be used in subtractive form
