Convert 47 to a Roman numeral

Roman Numeral Values are:
I = 1, V = 5, X = 10
L = 50, C = 100, D = 500,
M = 1,000

We start with a total letter value of 47

Subtract 47from 4 of X

We want 3 or less of a letter

We need to subtract

Write the next letter of L in front of X

+ XL = XL

1 letter X and 1 letter L gives us:

50 - 10 = 40

Total: 47 - 40 = 7


Subtract 7 by 1 of letter V

XL + V = XLV

1 of the letter V gives us

1 * 5 = 5

Total: 7 - 5 = 2


Subtract 2 by 2 of letter I

XLV + II = XLVII

2 of the letter I gives us

2 * 1 = 2

Total: 2 - 2 = 0


Since our total = 0, we have our answer

XLVII
