Sawed bought 21 1/2 pounds of ground beef he used one fourth or the beef to make tacos and two thirds of the remainder to make quarter pound burgers. How many burgers did he make?

Answer 1

21 and 1/2 = 43/2

3/4 remain after tacos ---> 2/3 * 3/4 = 6/12 = 1/2

so 1/4 of it for tacos

1/2 of it for 1/4 hamburgers

1/4 of it left over

1/2 * 43/2 = 43/4 = 10 and 3/4 pounds of beef for the 1/4 hamburgers

43/4 divided by 1/4 lb = 43/4 * 4/1 = 43

He made 43 of the 1/4 lb hamburgers
