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?

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

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 for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
