One-third of the students in mrs. hayko's class walk to school. of the students who do not walk to school, four-fifths take the bus. what fraction of the students in mrs. hayko's class take the bus to school? how many students might be there in her class.

1/3  of the students walks

1 -1/3 = 2/3   so 2/3 of the students do not walk

of the student who do not walk 4/5 take the bus

2/3 * 4/5 = 8/15  

8/15 of her students take the bus

There must be at least 15 student

We only want whole numbers of students, so they must be in multiples of 15

15,30,45,60 etc

Mrs H has either 15 or 30 students.  Higher multiples would be too many students in the class
