how can you make fractions on the culculater i am really curios

i REALLY want to know cuz i have fractions on my work

Just do this:

z*(x/y)

i.e.

4*(3/4)=3

Just enter them as you would write them down on a piece of paper, like this:

1/4 x 3/5, and press the = sign. It should give you the right answer.
