Let the total number of vehicles in the parking lot be 'z'. Therefore, the number of motorcycles = 0.80z The number of trucks = 0.20z According to the question: (Wheels of motorcycles) = 2 × 0.80z = 1.6z (Wheels of trucks(Wheels of trucks) = 4 × 0.20z = 0.8z Now, the ratio of the number of wheels of motorcycles to that of trucks: 16z/0.8z = 1.6/0.8 = 2/1 or 2:1 So, the ratio of the number of wheels of motorcycles to trucks is 2:1.
