<human>:  There are 92 students altogether. Twenty of them ride the school bus home together, 5/8 of the remaining ride their own bike home, and the rest whose houses are near the school walk home. How many students are walking home?
<bot>: How many students are left? ** If there are 92 students and 20 students take the bus home, the number of students who haven't taken the bus is 92-20 = <<92-20=72>>72 students.
How many students ride bikes home? ** 5/8 of the students who didn't take the bus home ride bikes home, a total of 5/8* 72 = <<5/8*72=45>>45 students.
How many students are walking home? ** The number of students who neither took the bus nor biked home but walked home is 72-45 = <<72-45=27>>27
