31.25
Because:
Percentage solution with steps:
Step 1: Our output value is 125.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above, \($125=100\%$. \)
Step 4: Similarly, \( $x=25\%$.\)
Step 5: This results in a pair of simple equations:
\($125=100\%(1)$. \)
\($x=25\%(2)$. \)
Step 6: By dividing equation 1 by equation 2 and noting that both the right hand side of both
equations have the same unit (%); we have
\($\frac{125}{x}=\frac{100\%}{25\%}$\)
Step 7: Again, the reciprocal of both sides gives
\($\frac{x}{125}=\frac{25}{100}$ \)
\($\Rightarrow x=31.25$ \)
Therefore, \($25\%$ \)of \($125$\) is \($31.25$\)
