Reading rules

1. Break the number (decompose it) into place value subgroups:

811,378 = 800,000 + 10,000 + 1,000 + 300 + 70 + 8;

2. Convert each subgroup:

800,000 = 500,000 + 100,000 + 100,000 + 100,000 = (D) + (C) + (C) + (C) = (D)(C)(C)(C);
10,000 = (X);
1,000 = M;
300 = 100 + 100 + 100 = C + C + C = CCC;
70 = 50 + 10 + 10 = L + X + X = LXX;
8 = 5 + 1 + 1 + 1 = V + I + I + I = VIII;

3. Wrap up the Roman numeral:

811,378 = 800,000 + 10,000 + 1,000 + 300 + 70 + 8 = (D)(C)(C)(C) + (X) + M + CCC + LXX + VIII = (D)(C)(C)(C)(X)MCCCLXXVIII;

Final answer:


811,378 = (D)(C)(C)(C)(X)MCCCLXXVIII
