Answer:
15/8
Explanation:

First, combine the mixed fraction. 2 (2/1) is equal to 8/4 (multiply by 4/4). This comes out as 9/4.
9/4 - 3/8
Then, we need to multiply the first fraction by 2/2 to get a common denominator
18/8 - 3/8
Since the denominators are the same, we can subtract the numerators, 18 - 3 = 15.
The denominator is kept after doing the subtraction in the numerator. 15/8 is the answer, or 1 7/8 as a mixed fraction
