So I recommend doing bar = bar over 100

so it would look like:
  18        x
------ = ------
  60      100

so you would cross multiply and get the equation 60x = 1800
You would solve for x, so 1800/60 equals 30, so it would be 30%
If you have questions about bar = bar over 100 ask me in the comments, hope this helps :)

18 is 30% of 60

Let the percentage of 60 that gives 18 as the result be x

x% of 60 is 18

That is:

x% of 60 = 18

This can be expressed mathematically as:

\(\frac{x}{100} \times 60 = 18\)

Simplify the expression shown above by multiplying both sides of the equation by 100

60x  = 18(100)

60x  =  1800

Divide both sides by 60

\(\frac{60x}{60} = \frac{1800}{60}\)

Simplifying the equation further

x  =  30

Therefore, 18 is 30% of 60
