The required unknown volume of the entire tank will be denoted by the conditional variable “X”.
Based on the conditions of the problem, we will form the following proportion: X liters of gasoline are related to 100% as 65 liters of gasoline are related to 20%.
Based on the existing proportion, we get the following equation: X x 20 = 100 x 65.
As a result of solving this equation, we get the following X = 100 x 65/20 = 5 x 65 = 325 liters of gasoline.
Answer: the entire volume of the tank is 325 liters of gasoline.
