First, we want to find how many students were expected to attend the field trip: 170 • ⁴/₅= 136 Next, we are told that 1/6 of the school gets the flu on the day of the field trip and can not leave their room. That means we should only expect 5/6 of the 136 students originally planning to attend to still attend the field trip. 136 • ⁵/₆ = 113.333, which rounds to 113.
