The small circle in the picture rolls(*except there’s not picture here;sorry) around the inside of the large circle. The small circle has radius 1 while the larger circle has radius 9/4. How many times must the small circle travel around the large circle before the points on the small and large circle labeled at A meet again?
4
Yes, but how would I solve it?
It’s a circumference problem. What is the least whole number that is a multiple of the little circle’s circumference that is equal to a whole number multiple of the large circle’s circumference?
Sorry that should be the least whole number that is a multiple of the large circle’s circumference etc etc
