Answer:
Susan is incorrect.
Step-by-step explanation:
First, what we do is add 1/8 + 3/5
Our result will be 4/13 because 1+3 = 4 would be as the numerator, and 8+5 = 13 would be as the denominator.
We can't simplify 4/13.
If we did increase the number, however, it would be 8/26, which is not close to the answer.
Therefore, Susan is incorrect.
