1.	10 points 2. Two wheels revolve around a common axis; bigger one makes 15 and smaller one makes 20 revolutions in a minute, respectively. Starting with a certain point on the circumference downwards. After how many revolutions will they come together in the same position?
Answer» Total number of revolutions=60.Step-by-step EXPLANATION:Time for one REVOLUTION = 60/15 =4 60/20 = 3 LCM of 4,3, 4,3 = 12. .= LCM of Numerators/HCF of Denominators = 60/1= 60.
