first off, let's convert the mixed fractions to "improper", and also recall that minus * minus is plus.
Hello!
Just to make this simpler, let's convert the fractions to decimals.
-3.5-(-12.25)
-- means add, so we will switch it to that.
-3.5+12.25
Now we add.
-3.5+12.25=8.75
.75 is 3.4.
Therefore, our answer is D) 8 3/4.
I hope this helps!
