$\sf Hello!$

•
$\sf Number\: of \:times \:head \:came\: up = 9$
•
$\sf Number \:of \:times \:coin \:is \:flipped = 20$

$\sf Relative\: frequency\: of \:head \:coming \:up$ :

=
$(\sf 9)/(\sf 20) × \sf 100$ %

=
$\sf 9 × 5$

=
$\sf 45$ %

=
$(\sf 45)/(\sf 100)$

=
$\sf 0.45$

$\sf Hence,$

$\sf Realtive\: frequency\: of\: head \:coming\: up\: is \:B.\:0.45$
