1. the number of girls in the club as a percentage of the total number of registered

athletes -

$40\%$

2. the ratio of girls : boys registered at the club. : -

=》2 : 3

Step-by-step explanation:

here's the solution : -

percentage of girls in the club :

=》

$\frac{total \: girls}{total \: athletes} \times 100$

=》

$\frac{48}{120} \times 100$

=》

$\frac{4800}{120}$

=》

$40\%$

so, 40 % of athletes are girls.

now,

number of boys = 120 - 48 = 72

ratio of girls : boys : -

$\frac{number \: of \: girls}{number \: of \: boys}$

=》

$\frac{48}{72}$

=》

$\frac{ {2} }{3}$

so, their ratio = 2 : 3
