Challenge! Ready? What is the solution to the proportion, 3y-8/12= y/5? Show me your work so that I, Lolly, know you are not cheating.

OpenStudy (anonymous):

first multiply both sides by 5

OpenStudy (anonymous):

so you get y=15y-40/12

OpenStudy (anonymous):

Then u multiplly both sides by 12

OpenStudy (anonymous):

u get 12y= 15y-40

OpenStudy (anonymous):

3y=40

OpenStudy (anonymous):

so y=13.3333

OpenStudy (anonymous):

It ends in a fraction.

OpenStudy (anonymous):

131/3

OpenStudy (anonymous):

13 and 1/3

OpenStudy (anonymous):

Something is off.

OpenStudy (anonymous):

OpenStudy (anonymous):

There are none. There is only one right possible answer.

OpenStudy (anonymous):

then it is 13 and 1/3

OpenStudy (anonymous):

OpenStudy (anonymous):

You are supposed to cross multiply I believe

OpenStudy (anonymous):

u get the same answer...

OpenStudy (anonymous):

Hmm. Let me see.

OpenStudy (anonymous):
