Ranking the divers based on the amount of oxygen left in their tanks from least to greatest is; Dante, Sofia, Alexis.
We are given the amount of oxygen left in each of the divers tanks as;
Amount left in Alexis Tank = 70⁹/₈ liters
Amount left in Dante's tank = 9.3 liters = 9³/₁₀ liters
Amount left in Sofia's Tank = 9⁸/₁₅ liters = 9.533 liters
Thus, ranking these amounts from least to greatest gives;
9.3 liters < 9⁸/₁₅ liters < 70⁹/₈ liters
Thus, ranking the divers based on the amount of oxygen left in their tanks from least to greatest is;
Dante, Sofia, Alexis.
