One third of the students in mrs. hayko's class walk to school. Of the students who do not walk, fourfifths take the bus.
a) what fraction of the students in Mrs. Hayko's class take the bus to school?
b) How many students might there be in her class?

So 2/3 of her students do NOT walk to school
of those (4/5) take the bus
so (4/5)(2/3) or 8/15 take the bus
The number of students must be a multiple of 15
In an enlightened board of education she would have 15 students,
in reality she probably has 30 students,
and , in some backwards regions, she could have 45 students. 
the answer will be 1/32
