6. convert each of the following from roman numerals to hindu-arabic numerals a. cxxviii b. xcdcccxxvii

A)128

B)717

Step-by-step explanation:

In Roman numerals each letter have a numerical value in Hindu-Arabic numerals.

These values are:

I = 1

V = 5

X = 10

L = 50

C =100

D = 500

M = 1000

a) CXXVIII = 100+10+10+5+1+1+1 = 128

b) XCDCCCXXVII = 500+100+100+10+10+7-100-10 = 717

In this question we subtracted the value of XC(-100-10) because it was preceding or appeared before a larger value and hence, we subtract these values from the value of DCCCXXVII(500+100+100+100+10+10+7).

This could be understood with the help of following example: If we calculate the value of CD it would be (500-100) = 400. Now, XCD = (400-10) = 390.
