There are 180 students playing basketball. 108 of them. First you have to find the amount of students that are girls. To do that, you have to subtract the total amount of students by the amount of boys.
[tex] 180-108 = 72 [/tex]
Now that you have have found the amount of girls, divide that amount by the total amount of students that are girls.
[tex] 72 \div 180 = 0.4 [/tex]
You have your answer as a decimal. All you need to do is convert it into a percent, which isn't pretty easy.
To change a decimal to a percent, move the decimal point 2 places to the right and add a percent sign.
[tex] 0.4 \rightarrow 40 \% [/tex]
40% of the students playing basketball are girls.
