Octal, binary, duodecimal, and decimal, to name but four.
The Romans used a duodecimal (base-12) system for fractions. You cannot notate 1/5 using duodecimal. The following notations are used for the 11 possible fractions used by the Romans using a series of dots and the letter S (for semis, or half): 1/12 = ● 1/6 = ●● 1/4 = ●●● 1/3 = ●●●● 5/12 = ●●●●● 1/2 = S 7/12 = S● 2/3 = S●● 3/4 = S●●● 5/6 = S●●●● 11/12 = S●●●●●
The place value of each digit is b times the place value of the digit to its right where b is the base for the system: whether that is binary, octal, decimal, duodecimal, hexadecimal, sexagesimal or some other value.
I am having a hard time understanding the duodecimal system.

There is no specific name. And it is not "duodecimal" since the number 12 is not a duodecimal "digit".

Duodecimal
Octal, binary, duodecimal, and decimal, to name but four.
The duodecimal system, also known as base-12, is a numeral system that uses twelve as its base. It is similar to the decimal system (base-10) that we commonly use, but with twelve digits instead of ten. Some argue that a base-12 system could be more efficient than base-10 for certain calculations and measurements.
Any number that has a fraction that is not duodecimal (twelfths or factors thereof).
