Sam is having a party and he will make 14 hamburgers each hamburger requires 2/7 pound of meat how much meat does Sam need and total for the party

To find out how much meat Sam needs for the party, multiply the number of hamburgers by the amount of meat needed for each hamburger:

14 hamburgers * (2/7 pound of meat per hamburger) = 28/7 pounds of meat

To simplify this, divide 28 by 7 to get:
28/7 = 4 pounds of meat

So, Sam needs 4 pounds of meat for the party in total.
