Roman Number - Roman numerals, any of the symbols utilized in the system of numerical notation supported the traditional Roman system. 
         The symbols are I, V, X, L, C, D, and M, which stand for 1, 5, 10, 50, 100, 500 and 1,000 respectively in the Hindu-Arabic numeral system. 

         A symbol placed after the same or greater value adds its value; For example, I =  1, II = 2, V = 5, X = 10 and LX = 60. A symbol placed before more than one value subtracts its value; For example, IV = 4, XL = 40, and CD = 400. A bar placed on a number multiplies its value by 1,000.

= Convert Hindi Arabic Number into Roman Number Name With Expanded Form Method.

A) -  11
Solve - Expanded Form, 11 = 10 + 1
                      Now, Fill The Roman Number 10 = X And 1 = I
                      So, 11 = 10 + 1
                                  = X + I
                Answer is = XI

B) - 35
Solve - Expanded Form, 35 = 30 + 5
                      Now, Fill The Roman Number 30 = XXX And 5 = V
                      So, 35 = 30 + 5
                                  = XXX + V
                Answer is = XXXV

C) - 65
Solve - Expanded Form, 65 = 60 + 5
                      Now, Fill The Roman Number 60 = LX And 5 = V
                      So, 65 = 60 + 5
                                  = LX + V
                Answer is = LXV

D) - 97
Solve - Expanded Form, 97 = 90 + 7
                      Now, Fill The Roman Number 90 = XC And 7 = VII
                      So, 97 = 90 + 7
                                  = XC + VII
                Answer is = XCVII

E) - 174
Solve - Expanded Form, 174 = 100 + 70 + 4
                      Now, Fill The Roman Number 100 = C, 70 = LXX And 4 = IV
                      So, 174 = 100 + 70 + 4
                                  = C + LXX + IV
                Answer is = CLXXIV

F) - 2965
Solve - Expanded Form, 2965 = 2000 + 900 + 60 + 5
                      Now, Fill The Roman Number 2000 = MM, 900 = CM,60 = LX And 5 = V
                      So, 2965 = 2000 + 900 + 60 + 5
                                  = MM + CM + LX + V
                Answer is = MMCMLXV

G) - 9865
Solve - Expanded Form, 2965 = 9000 + 800 + 60 + 5
                      Now, Fill The Roman Number 9000 = MX, 800 = DCCC,60 = LX And 5 = V
                      So, 2965 = 9000 + 800 + 60 + 5
                                  = MX + DCCC + LX + V
                Answer is = MXDCCCLXV
