How do you solve #\frac { r } { 18} = \frac { 3} { 27}#?

Answer 1

#r=2#

The easiest way is to cross multiply:

#27r=54#
#r=54/27#
#r=2#

Answer 2

One way is to cross-multiply, simplify and then isolate #r#. In this case, #r=2#.

One way to solve for #r# is to cross-multiply and isolate #r#.

#r/18 = 3/27#

To cross multiply...

#27r = 3(18)#

Now we simplify.

#27r = 54#

And then isolate #r#.

#(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 :)

Answer 3

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.
