Question

One third of the students in mrs. hayko's class walk to school. Of the students who do not walk, four-fifths 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?

Answer 1

So 2/3 of her students do NOT walk to school
of those (4/5) take the bus

so (4/5)(2/3) or <b>8/15 take the bus</b>

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.

Answer 2

the answer will be 1/32
