Question: What is 12.5 percent of 40?
Percentage solution with steps:
Step 1: Our output value is 40.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$40=100\%$.
Step 4: Similarly, $x=12.5\%$.
Step 5: This results in a pair of simple equations:
$40=100\%(1)$.
$x=12.5\%(2)$.
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
$\frac{40}{x}=\frac{100\%}{12.5\%}$

$\frac{x}{40}=\frac{12.5}{100}$
$\Rightarrow x=5$
Therefore, $12.5\%$ of $40$ is $5$
