What is the solution to r over two is equal to one over three?

OpenStudy (cwrw238):

r/2 = 1/3 cross multiply: 3r = 2 now divide both sides by 3 to find r

OpenStudy (anonymous):

ty

OpenStudy (cwrw238):

yw

OpenStudy (anonymous):

wait... I don't get it

OpenStudy (anonymous):

What do you not get?

OpenStudy (anonymous):

the divide both sides by 3 to get r

OpenStudy (anonymous):

yeah, i know i suck at math

OpenStudy (anonymous):

So you divide 2 by 3

OpenStudy (anonymous):

ok.

OpenStudy (anonymous):

and then do i dived 3r by 3?

OpenStudy (anonymous):

hello?

OpenStudy (anonymous):

\[\frac{r}{2}=\frac{1}{3} \]Multiiply each side by 6 and simplify.\[3r=2 \]Now solve for r.

OpenStudy (anonymous):

yeah i know, but i don't know how to do that

OpenStudy (anonymous):

Yes, the r needs to be isolated so when you divide 3r by 3 it becomes r

OpenStudy (anonymous):

Version 2. I made a bad. Yes, divide each side by the number that is in front of r, which is 3. The 3 divides out on the LHS and the RHS is 2/3, the problem answer.

OpenStudy (anonymous):

Or 0.67

OpenStudy (anonymous):

thank you!
