One way is to cross-multiply, simplify and then isolate
One way to solve for
#r/18 = 3/27#
To cross multiply...
#27r = 3(18)#
Now we simplify.
#27r = 54#
And then isolate
#(27r)/27 = 54/27#
#r = 2# We can double check our work by subbing in
#r=2# into the original equation.
#r/18 = 3/27#
#(2)/18 = 3/27#
#1/9=1/9# Thus, we can conclude that
#r=2# .Hope this helps :)

To solve the equation ( \frac{r}{18} = \frac{3}{27} ), you can cross multiply to find the value of ( r ).
Cross multiplying: [ r \times 27 = 3 \times 18 ]
Solving for ( r ): [ 27r = 54 ]
Divide both sides by 27: [ r = \frac{54}{27} ]
Simplify: [ r = 2 ]
Therefore, the solution to the equation is ( r = 2 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
