Question

Jeff has 10 packages that he wants to mail. 9 identical packages weigh 2 7/8

pounds each. A tenth package weighs two times as much as one of the other packages. How many pounds do all ten packages weigh?​

Answer 1

The weight of the 9 identical packages is 9 x 2 7/8 = 25 7/8 pounds.

If one package weighs 2 7/8 pounds, then the tenth package weighs 2 x 2 7/8 = 5 6/8 pounds.

Adding the weight of all ten packages, we get 25 7/8 + 5 6/8 = 31 13/16 pounds.

Therefore, all ten packages weigh 31 13/16 pounds.
