I would like to know how to explicitly indicate a fraction if there is a problem of division? I've been using that method and I believe I'm getting some conflicting results, but I'm just learning, so I'm unsure.
To indicate a fraction, simply add the parenthesis () and add the divide symbol and the values. I have just installed the application and it works just fine. I recommended this way because the application doesn't have the proper button to indicate fractions and the solution I have posted works the same as you've just used the fractions symbol.
