What is 12.1 repeating as a fraction in simplest form?

If u have 1 number repeating, like 0.1111, then u put that 1 number over 9so it would be 1/9

if u have 2 numbers repeating, like 0.2323then u put ur 2 numbers over 99so it would be 23/99

if u have 3 numbers repeating, like 0.324324...then u put ur 3 numbers over 999...so it would be 324/999.
