Question

The first basic Roman numeral is

a. 0
b. I
c. V
d. X

Answer 1

Hint: In this type of problem, you must remember the Roman numeral system as well as their seven basic symbols. As we know that these symbols are used to represent any fixed positive integer. Therefore we can represent any fixed positive integer using these seven basic symbols into Roman numeral system

Complete step-by-step answer:

We know that the Roman numeral is a numeral system that originated in ancient Rome.
In this numeral system, there are seven basic symbols: I, V, X, L, C, D, M, with the fixed positive integer value that is used to represent a number
Symbol value

$\begin{align}
  & I \\
 & V \\
 & X \\
 & L \\
 & C \\
 & D \\
 & M \\
\end{align}$ \[\begin{align}
  & 1 \\
 & 5 \\
 & 10 \\
 & 50 \\
 & 100 \\
 & 500 \\
 & 1000 \\
\end{align}\]



So the first basic Roman numeral is I

Hence the correct option of this question is option (b).

Note: (1) The number 0 does not have its own Roman numeral
(2) The Roman also used fractions, the most common base for fraction was , which in Latin called Ounce.
 (3) You can represent any fixed positive integer in Roman numeral. Let’s take some numbers and try to represent them in Roman numeral form.
Example: (a) 37
(a)37
 In example (a) we have to convert 37 into Roman numeral
We can also write 37 as
37=10+10+10+5+1+1
Here we decomposed 37 into such forms so that we get such numbers which are directly represented by seven basic Roman numeral symbols.
10 is represented by X, 5 is represented by V, and 1 is represented by I
So,
37=10+10+10+5+1+1
  =X + X+ X+ V+I+I
  =XXXVII
