Answer/Step-by-step explanation:
If the Diver started at 85 3/4 below sea level (-85 3/4 from sea level.) And he descends more you have to find the difference between two distances.
In order to get to -103 1/5, how much was subtracted from the original distance of -85 3/4. To solve this use an inverse operation. Find the absolute value of the new distance and add the original distance from sea level.
I -103 1/5 I + -85 3/4 = 103 1/5 - 85 3/4 = 17.45.
The distance from each value is I 17.45 I So, the diver descended another 17.45 meters from sea level.
