60 hamburgers. If Morgan needs to

make 100 hamburgers for the

picnic, how much hamburger meat

does she need to buy?

Answer 1

Answer:

25 pounds of hamburger meat will make 100 hamburgers

Step-by-step explanation:

if 15 pounds of hamburger meat will make 60 hamburgers then

 1 pound of hamburger meat will make,

      15 pounds of hamburger meat ------------------------ 60 hamburgers

       1 pound of hamburger meat ---------------------- ? (X)

by cross multiplying, 60 * 1 = 15 * (X)

                                   60 = 15(X)

      (X) = 60 / 15 = 4,

therefore,  1 pound of hamburger meat ------------------- 4 hamburgers.

so, ? (X) pound of hamburger meat -------------------- 100 hamburger

also by cross multiplying from above,

                   100 * 1 = 4 * (X)

                     100 = 4 (X)

therefore (X) = 100 / 4 = 25

so, 25 pounds of hamburger meat will make 100 hamburgers
