Do you understand how to add fractions? If so, then just use the same procedure in your program that you would use on paper. If you don't know how to add fractions, go here.

the problem is when I am adding 1/2 +3/4 or 1.0 + 3.0 it can't read my input.

and i don't know why it can read my numbers.

I need that my answer be like with fraction (ex: 3/4)

you need to do it like you would on paper as said earlier..... find a common denominator, calculate the new numerators then add those numerators... you have to split the fractions at the / sign. then just stick it back in after your done doing allt he steps.

A man I am getting my answer with pointer( ex: 1.25). How can I change 1.25 in to 5/4 in java language. Can you help me with showing me a small function that I can use in my program.

Thanks

no where in there do you convert to decimal or use decimals.
