we know the seagull starts at 24 1/2 above sea level, which makes it positive. Since it goes -47 2/3, that means it goes that far down. Since 2/3 and 1/2 won’t easily go together, we can first change our values to 24 3/6 and -47 4/6, since six is the gcf, or greatest common factor. This makes the problem super easy. We need to find the elevation at the end, which we can call X. X = 24 3/6 - 47 4/6. We can solve that out with simple multiplication and we find the elevation of the seagull at the end is -23 1/6 feet, which is 23 1/6 below sea level.
