Debora [2.8K]

Answer:

The fraction of the students that walk in in Marla's school  is equal to \frac{2}{9}

Step-by-step explanation:

Let

x------> the total students in Marla's school

we know that

The number of students that not ride the bus is equal to

\frac{6}{15}x\ students

The number of students that walk to the school is equal to

\frac{6}{15}x*\frac{5}{9}=\frac{2}{9}x\ students

therefore

The fraction of the students that walk in in Marla's school  is equal to \frac{2}{9}
