$9 \frac{3}{4}$

#### Explanation:

$\textcolor{b l u e}{\text{Preamble}}$

The symbol % is a bit like a unit of measurement but one that is worth $\frac{1}{100}$

so 39%" is the same as "39xx1/100=39/100

In the same way that (as an example)

40/100 =40xx1/100 = 40 xx% = 40%#

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$\textcolor{b l u e}{\text{Answering the question}}$

39% of 25 is the same as $\frac{39}{100} \times 25$

You can write this as $39 \times \frac{25}{100}$

but $\frac{25}{100}$ is the same as $\frac{1}{4}$ giving:

$39 \times \frac{1}{4} \text{ "=" " 39/4" " =" } 9 \frac{3}{4}$
