How to Write 139 in Roman Numerals?
To convert 139 in Roman Numerals, we need to represent 139 as the sum of the fundamental symbols. 139 is nothing but 100 + 30 + 9. But neither 30 nor 1 have fundamental Roman numerals. So let’s split them again, 30 as sum of 3 tens and 9 as the difference of 10 and 1. Representing them numerically;
139 = 100 + 30 + 9
139 = 100 + (10 + 10 + 10) + (10 – 1)
139 = C + ( X + X + X) + (X – I)
139 = C + X + X + X + (IX)
139 = CXXXIX.
