.
Forty percent of the students at the basketball club are girls. There are 72 boys at the club. How many girls are there
~~~~~~~~~~~~~~~~~


&lt;pre&gt;
1.  Since forty percents of the students at the basketball club are girls, 60% are boys.

    So, you have this equation 0.6x = 72, where x is the total number of students at the basketball club.

    The solution of this equation is x = {{{72/0.6}}} = 120.

    Thus there are 120 students in the club.


2.  Hence, the number of girls is 120 - 72 = 48.
&lt;/pre&gt;
