XXV represents the number 25.

Let’s break it down:

X = 10

XX = 10 + 10 = 20

V = 5

So, XXV = 10 + 10 + 5 = 25

X = 10

XX = 10 + 10 = 20

V = 5

I = 1

II = 1 + 1 = 2

III = 1 + 1 + 1 = 3

So, XXVIII = 10 + 10 + 5 + 1 + 1 + 1 = 28

How to Convert XXVIII Roman Numerals to a Number?

To find the number value of XXVIII in Roman numerals you can use either of these two simple methods :

Method 1:

XXVIII
= X + X + V + I + I + I
= 10 + 10 + 5 + 1 + 1 + 1
= 28

Method 2:
