Answer:
The answer is 4.
Step-by-step explanation:
Since the fractions have the same denominators, all you have to do is subtract 1/5 from 1/5. When you subtract the numerators (1-1) you get 0. That would make the fraction 0/5, but that does not have to be included in the answer since it has no value. Subtract the whole numbers (23-19) to get 4.
