There were $52$ girls in the hall.

#### Explanation:

To determine 80% of the total number of $65$ students, we write:

$x = 65 \times \frac{80}{100}$

$x = 65 \times \frac{8 \cancel{0}}{10 \cancel{0}}$

$x = 65 \times \frac{8}{10}$

$x = \frac{520}{10}$

$x = \frac{52 \cancel{0}}{1 \cancel{0}}$

$x = 52$
