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 $$31.25$$
