17/56 So to make sure that you are subtracting right, you make the denominators the same. So the denominator is 56 because it is a common number for 7 and eight. And then whatever you do to the bottom you got to do to top so time seven by eight and 4 which is 49 and 24 so 49-24 is 17/56 so the answer would be this because you can’t simplify the answer down.
