ANSWER KEY
B
Practice Set
1) Chef Joe has 8 lb 4 oz of ground beef in his freezer. This is ⅓ of the amount needed
to make the number of burgers he planned for a party. If he uses 4 oz of beef for each
burger, how many burgers is he planning to make? Justify your answer with equations
and a visual model.
8 lbs 4 oz x 3 = 24 lbs 12 oz
24 lb x 16 = 384 oz
384 oz + 12 oz = 396 oz
Number of burgers = B
396 ÷ 4 = B
99 = B
2) Diego and Charley have three dogs. Diesel weighs 89 pounds 12 ounces. Ebony
weighs 33 pounds 14 ounces less than Diesel. Luna is the smallest at 10 pounds 2
ounces. What is the combined weight of the three dogs? Justify your answer with
equations and a visual model.
Diesel’s weight = D
89 lbs x 16 = 1,424 oz
1,424 oz + 12 oz = D
1,436 oz = D
Ebony’s weight = E
33 lbs x 16 = 528 oz
528 oz + 14 oz = 542 oz
1,436 oz - 542 oz = E
894 oz = E
Luna’s weight = L
10 lbs x 16 = 160 lbs
160 lbs + 2 oz = L
162 oz = L
Total weight = W
1,436 oz + 894 oz + 162 oz = W
2,492 oz = W
3) Five ounces of pretzels are put into each bag. How many full bags can be made
from 22 ¾ pounds of pretzels? Justify your answer with equations and a visual model.
22 lbs x 16 = 352 oz
¾ lb = 12 oz
352 oz + 12 oz = 364 oz
Number of bags = B
364 oz ÷ 5 oz = B
72 r4 = B
You will be able to fill 72 full bags of pretzel dough. There will be 4 ounces left
over.
