1/3r = 3/4
multiply both sides by 3
1/r = 9/4
r = 4/9

1/3r=3/4
you divide both sides by 1/3
r=3/4 divided by 1/3
r=2.25

First, divide by 1/3 on each side...
so you get :
3/4 divided by 1/3 then you flip 1/3 over to its recipricol so it is 3/1 then you MULTIPY 3/1 by 3/4 and you get
9/4 as your answer

solve for r
r= 3/1 * (3/4) = 9/4

you have to get r by itself...to do that you have to multiply by 3.
whatever you do to one side you have to do to the other so multiply both sides by 3 and you get r=9/4
