Question: What is 18 percent of 30?

Percentage solution with steps:

Step 1: Our output value is 30.

Step 2: We represent the unknown value with {x}.

Step 3: From step 1 above,{30}={100\%}.

Step 4: Similarly, {x}={18\%}.

Step 5: This results in a pair of simple equations:

{30}={100\%}(1).

{x}={18\%}(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have

\frac{30}{x}=\frac{100\%}{18\%}

Step 7: Again, the reciprocal of both sides gives

\frac{x}{30}=\frac{18}{100}

\Rightarrow{x} = {5.4}
