The byrds. you have 16 new cds to put on your empty five-shelf cd rack. can you place the cds so that each shelf contains three or fewer cds? can you arrange them so that each shelf contains exactly three?

Step-by-step explanation:

In this question we have given

Total number of CDs to put on empty shelf CD rack=16

Number or shelf in a CD rack=5

part 1:

Can you place the CDs so that each shelf contains three or fewer CDs

No we cannot place the CDs in such a manner that each shelf contains three or fewer CDs because there are 16 CDs which we have to keep in 5 shelf so each shelf will contains at least 3 CDs and one shelf will contains 4 CDs(Because=). If we place 3 or less CDs in each shelf than 15 or less than 15 CDs can be kept in all the 5 shelf

Part 2

Can you arrange them so that each shelf contains exactly three?

Answer :

No We cannot arrange them so that each shelf contains exactly three if we do so than 1 CD will be remain outside the shelf as

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
