How do you take a (-) fraction and add a (+) fraction? Exp -7/4+3/4
you have to make the denominators the same, in this case they are, so you can just add them together.
-7+3=-4
its the same as 3-7
but you just have to include the denominator so it is -7/4 + -3/4 = -4/4 which is -1/1 = -1
hope that helps
