Answer:
1/5 closer to the observatory than Jimmy.
Explanation:
If the question is asking how much closer to the observatory Sylvia is than Jimmy, we can use simple math.
Jimmy's distance is 6/10.
However, Sylvia's is 2/5. But we can turn that into a fraction with the same denominator as Jimmy's distance.
It would be 4/10.
Subtracting 4/10 from 6/10, you get 2/10, or 1/5.
Sylvia is 1/5 closer to the observatory than Jimmy.
