Question

Scrie in cifre romane numerele: 1859,1877,1918

Answer 1

Răspuns:

• 1859 = MDCCCLIX

• 1877 = MDCCCLXXVII

• 1918 = MCMXVIII

Explicație pas cu pas:

Cifrele romane sunt :

• I = 1;
• V = 5;
• X = 10;
• L = 50;
• C = 100;
• D = 500;
• M = 1000;

❃ 1859 = MDCCCLIX ❃

1859 = 1000 + 800 + 50 + 9

1000 = M

800 = 500 + 100 + 100 + 100 = D + C + C + C = DCCC

50 = L

9 = 10 - 1 = X - I = IX

1859 =  1000 + 800 + 50 + 9 =  M + DCCC + L + IX = MDCCCLIX

❃ 1877 = MDCCCLXXVII ❃

1877 = 1000 + 800 + 70 + 7

1000 = M

800 = 500 + 100 + 100 + 100 = D + C + C + C = DCCC

70 = 50 + 10 + 10 = L + X + X = LXX

7 = 5 + 1 + 1 = V + I + I = VII

1877 = 1000 + 800 + 70 + 7 = M + DCCC + LXX + VII = MDCCCLXXVII

❃ 1918 = MCMXVIII ❃

1918 = 1000 + 900 + 10 + 8

1000 = M

900 = 1000 - 100 = M - C = CM

10 = X

8 = 5 + 1 + 1 + 1 = V + I + I + I = VIII

1918 = 1000 + 900 + 10 + 8 = M + CM + X + VIII = MCMXVIII
