Question

Represente com nosso algarismo os números romanos a seguir:
A) CMXX
B) XXVIII
C) XLI
D) MCDX
E) XCV
F) LXXVIII

Answer 1

A) CMXX = 920
C = 100; M = 1000; X = 10

1000-100+10+10 = 920

B) XXVIII = 28
X =10; V = 5; I = 1

10+10+5+1+1+1 = 28

C) XLI = 41
X =10; L = 50; I = 1

50-10+1 = 41

D) MCDX = 1410
M = 1000; C = 100; D = 500; X =10

1000+500-100+10 = 1410

E) XCV = 95
X = 10; C = 100; V = 5

100-10+5 = 95

F) LXXVIII = 78
L = 50; X = 10; V = 5; I = 1

50+10+10+5+1+1+1 = 78
