Let us first try to add the fractions and arrive at the answer.
Taking LCD of 18 and 20, we get LCD = 180
Now, making denominators of each fraction equal to 180 and changing the numerators accordingly.
Therefore, the result of Alaina is not correct because she got an answer which is less than the fraction . But when we add two fractions, the result must be greater than either of the addend.
Therefore, her answer is not correct because the sum cannot be less than either addend.
