Question

Last summer,Karl went to the beach every 2 days. Antonia went to the beach every 3 days.

How often did they see each other at the beach?

Answer 1

They see each other every 6 days. You just need to find the LCM of 2 & 3 which is 6.

Hope I helped:P

Answer 2

I think it would be every six days because if you count by threes and then by twos you get six both times and they would see each other on the sixth day.   Hope that helped you :D
