Gears

The gearing fits the wheel with 20 teeth to the wheel with 36 teeth. Before starting, the machine is painted tooth smaller wheels in the designated space between the teeth of the larger wheels. How many times after starting the machine wheels turning that painted teeth again fits into the designated spaces?

Correct answer:

n1 =  9
n2 =  5

Step-by-step explanation:

20=225 36=2232 LCM(20,36)=22325=180  a=LCM(20,36)=180 n1=a/20=180/20=9
n2=a/36=180/36=5
