Answer :
7 3 4
-- + -- = -----
8 8 8
7/8 - -3/8 = 4/8
When subtracting fractions, you only subtract the top numbers (numerators) as long as the bottom numbers (denominators) match.
But, when subtracting a negative number, the two negatives cancel each other out. Instead you add it.
7-3=4
7/8-3/8=4/8
7/8+3/8=10/8=1 2/8
7/8 - -3/8= 1 1/4
