At Rainbow Preschool, there are 80 students.  25% of them are half-day students and get picked up at noon, while the rest are full-day students. How many are full-day students?
Number of half day preschoolers is 80 x 25% = <<80*25*.01=20>>20 students.
Number of full day preschoolers is 80 - 20 = <<80-20=60>>60 students.
