Answer:

r=3

Explanation:

Divide the numbers

2/r=12/18

2/r=2/3

Multiply all terms by the same value to eliminate fraction denominators

rx2/r=rx2/3

simplify

2=2r/3

multiply all terms by the same value to eliminate fraction denominators again

3x2=3x2r/3

simplify

6=2r

divide both sides if the equation by the same term

6/2=2r/2

r=3
