What is the ratio of the length of your swing to the length of another swing?

You go to the park with one of your friends and decide to play on the swings. Your swings start out together, but you notice that they don't stay together. After your swing has completed 15 complete cycles, your friend's swing has made only 13.5 cycles. What is the ratio of the length of your swing to the length of your friend's swing?|||ratio has to be in whole numbers....so multiply both by 2



30:27 simplify (div by 3) = 10:9
