Answer:
The net gain is 1 point
Explanation:
The equation is
stock= -8 1/4 -2 3/4 + 12
To get the result we have to get all the number with the same factor
So, 8 1/4, you multiple 8 x 4 =32 and added to 1/4, then 33/4
We make the same with the others.
stock= -33/4- 11/4+48/4
stock=-44/4 +48/4
stock=4/4=1
stock=1
