Question: 18 is what percent of 72?

Percentage solution with steps:

Step 1: We make the assumption that 72 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=72$.

Step 4: In the same vein, $x\%=18$.

Step 5: This gives us a pair of simple equations:

$100\%=72(1)$.

$x\%=18(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{72}{18}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{18}{72}$

$\Rightarrow x=25\%$

Therefore, $18$ is $25\%$ of $72$.
