The original number was 2000

Write $3 \frac{1}{4}$ $3 1/4$ as $3.25$ $3.25$

Write $3 \frac{1}{4} % as \frac{3.25}{100}$ $3 1/4%" as " 3.25/100$

Let the original number be $x$ $x$

Then we have: $\frac{3.25}{100} \times x = 65$ $3.25/100xx x= 65$

$\Rightarrow x = 65 \times \frac{100}{3.25}$ $=>x=65xx100/3.25$

$x = 2000$ $x=2000$
