Many advanced calculators have a fraction feature that will simplify fractions for you.

You are to write a program that will accept for input a non-negative integer as a numerator and a positive integer as a denominator, and output the fraction in simplest form. That is, the fraction cannot be reduced any further, and the numerator will be less than the denominator. You can assume that all input numerators and denominators will produce valid fractions.

    I'm always getting the third test case wrong but my code looks fine by me. I ran it by multiple g5 improper to mixed fractions worksheets and they've all worked; would appreciate anyone who can help.

      I had the same problem, run your code with this input 12 42. Your output will most probably be 0 2/7. You should not be printing 0's in these cases.

    For those getting presentation error make sure to print a newline at the end

      On sample 4, your most recent submission outputs "5 5/10" instead of "5 1/2"

    For test case 4 it's 4 0/3 which is just 4 but I keep getting it wrong. Help

      Your code suffers from precision issues (that is, a value of 1 in double ends up being "stored" as 0.9999999.... and that gets rounded down)

      As a good rule of thumb, whenever you can avoid floating point arithmetic, you should.

    If the answer turns out to be 0 and a fraction, do we just need to print 0? I keep getting a wrong answer on the answers with 0 in them

      If the answer is 0 1/2, don't print the 0
