Mary's pig can run the track in 4 minutes. Wendy's pig can run the track in 6 minutes. How many minutes will it take the two pigs to run the track and finish at the same time?

The least common multiple of 4 and 6 is 12.
In 12 minutes Mary's pig will make 12:4 = 3 full circles while Wendy's pig will make 12:6 = 2 circles and they will both finish at the same time.
