Question

write the following roman numeral as a hindu-arabic numeral: CLXXXVII

Answer 1

First we need to know the value of each letter:

I = 1

V = 5

X = 10

L = 50

C = 100

Then, we have that:

$\begin{gathered} \text{CLXXXVII}=100+50+10+10+10+5+1+1 \\ =187 \end{gathered}$

So the value of this number is 187.
