Answer:
0.4 or 2/5
Explanation:
The fractions already have the same denominator so all that is left to do is add the numerators
-4+6=2
2/5
when adding a positive to a negative, you can reverse the order so that you can remove the addition sign:
so instead of -4/5 + 6/5
you can make it 6/5 - 4/5 which equals 2/5 or .4
