<human>:  There are 100 people in a theater. If 19 of these people have blue eyes, half of them have brown eyes, a quarter have black eyes, and the rest have green eyes, how many of them have green eyes?
<bot>: How many people have brown eyes? ** 100/2 = <<100/2=50>>50 people in the theater have brown eyes.
How many people have black eyes? ** 100/4 = <<100/4=25>>25 people in the theater have black eyes.
How many people have brown, black, or blue eyes? ** There are 50+25+19 = <<50+25+19=94>>94 people in the theater with either brown, black, or blue eyes.
How many of them have green eyes? ** There are 100-94 = <<100-94=6>>6 people in the theater with green eyes.
