Answer:

-5/8

Explanation:

So basically with fractions that have different denominators you have to find the GCF (greatest common factor) of both of them, in this case 8 would be a GCF because it you times 4 and 2 you get a whole number of 8. since we found out the GCF we want to set them equal. so take the 1/4 and multiply both the top and bottom by 2, so we end with 2/8. You set the equation back up (-7/8) + (2/8). and combine the numerators -7+2/8 which ends you with with the answer of (-5/8) :)
