Periodic fraction gets converted to int

What I want to do is to devide 27 by ⁴/₃.
Unity turns ⁴/₃ to 1 and I don’t want it to be this way. I want Unity to do the math without converting ⁴/₃ to an int. How to do that?

Type float division = 27/(4/3f);. The f forces the evaluation to be on floating point numbers.
