Answer: Using operations with fractions, the diver's final location is:
- 60 3/4 meters relative to the surface of the water (60 3/4 meters below the surface of the water).
Solution:
Initial location: -50 1/4 meters
He descends another 10 1/2 meters: -10 1/2 meters
Final location = Initial location - 10 1/2 meters
Final location = - 50 1/4 meters - 10 1/2 meters
Final location = - (50+10) (1/4+1/2) meters
Final location = - 60 [(1)(1)+2(1)]/4 meters
Final location = - 60 (1+2)/4 meters
Final location = - 60 3/4 meters
