Question: What is 25 percent of 80?
Percentage solution with steps:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$80=100\%$.
Step 4: Similarly, $x=25\%$.
Step 5: This results in a pair of simple equations:
$80=100\%(1)$.
$x=25\%(2)$.
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
$\frac{80}{x}=\frac{100\%}{25\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{80}=\frac{25}{100}$
$\Rightarrow x=20$
Therefore, $25\%$ of $80$ is $20$
