Answer:
Position of the submarine now relative to the water surface 
Step-by-step explanation:
It says that the position of a submarine relative to the water surface was -32 1/4 feet . A downward navigational maneuver increased it's depth by 15 1/2 feet.
Now we need to find about what is the position of the submarine now relative to the water surface.
Downward navigation means we 15 1/2 is negative
so we will just add both values to get the final answer:
Position of the submarine now relative to the water surface = 


3/7 = 0.43 (approx.)
4/9 = 0.44 (approx.)
Hence, 4/9 is bigger.
It is 9 because you need to triple 3 so 3x3 is 9
N = 7 is the answerHope this helps
