<human>:  How many girls are in the school if 40% of a school population is made up of 240 boys?
<bot>: How many girls are in the school? ** 100% - 40% = 60% of the school's population are girls.
How many students are in 1% of the school? ** Since 40% is equal to 240 students, then 1% is equal to 240/40 = <<240/40=6>>6 students.
How many girls are in the school? ** Hence, there are 60 x 6 = <<60*6=360>>360 girls.
