Answer:
We have to make sure the denominators are equal.
Since 2 is evenly divided by 8, we can multiply just one term to get a common denominator.
Multiply 1 by 4, and get 4, then we multiply 2 by 4 and get 8.
x4
So you multply 1/2 4/8 (muliply numerator)
x4
1/2 x 4/8 (multiply denominator
now 3/8+4/8
since denominators match you can add
3+4=7 so its 7/8
