At the parking stand of Ram Leela ground, Kartik counted that there are 115 cycles, 75 scooters and 45 bikes. Find the ratio of the number of cycles to the total number of vehicles.
Number of cycles = 115
Number of scooters = 75
Number of bikes = 45
Total number of vehicles = Number of cycles + Number of scooters + Number of bikes
Total number of vehicles = 115 +75 + 45 = 235
ratio of the number of cycles to the total number of vehicles = 
⇒ ratio = 
Divide numerator and denominator by 5 we get
⇒ ratio = 
Therefore, ratio of the number of cycles to the total number of vehicles is 23:47
