Question

1=2 divided by 3 times r

Answer 1

$1= \frac{2}{3r}$ --> $3r = 2$ --> $r=2/3$

Answer 2

1= 2/3(r)
1=2/3r < it would look like that
Now if your solving for r then:

What you would do is multiply each side by 3r
You would get: 3r=2
Next you would divide each side by 3
You would get: r= 2/3
