Question

Rope packaged in 80-foot lengths

must be cut into 12-foot pieces to
do a certain job. If 28 such pieces
of rope are needed for the job, how
many packages of rope are needed?
(A) 4
(B) 5
(C) 6
(D) 7
(E) 28

Answer 1

it would be 5

Explanation:

any of the answer could have really worked (not 4 since that gives you less then what is needed) but in the end it would have been 5 because 5 leaves you with only 5.33 feet of rope left

80* any one of the four numbers (ex: 5) = your answer that you got (ex: 400)

then you divide that number by 28 (ex: 33.33) and if you want to go the extra mile then do the number that you got by dividing 28 minis the number of rope pieces needed

the whole thing >

80* 5 = 400

400/28 = 33.33

33.33- 28 = 5.33

hope this helps! :)
