Given: A school is hosting a story telling competition. A total of $15$ girls participated in the competition. Given that, out of all the participants, $37.5$ % are girls.

To do: To find the total number of participants.

Solution:

As given, Number of girls participants$=15$

Percentage of the girls in the competition$=37.5$ %

Let $x$ be the number of total participants.

$\Rightarrow x\times\frac{37.5}{100}=15$

$\Rightarrow x\times37.5=15\times100$

$\Rightarrow x=\frac{37.5\times100}{15}$

$\Rightarrow x=250$

Thus, total number of participants is $250$.
