ANSWER:
5%
EXPLANATION:
STEP 1:our output value is 20
STEP 2:we represent the unknown value with X
STEP 3:From step 1 above,20 =100%
STEP 4: Similarly X = 25%
STEP 5:This result results in a pair of simple equations:
$20=100\%(1)$.
$x=25\%(2)$.
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
$\frac{20}{x}=\frac{100\%}{25\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{20}=\frac{25}{100}$
$\Rightarrow x=5$
Therefore, $25\%$ of $20$ is $5$
