max2010maxim [7]

Answer:

12

Step-by-step explanation:

La clase entera es 1.

1/3 estudian español.

1/9 estudian italiano.

1 - 1/3 - 1/9 estudian alemán.

<em>5/9 de los estudiantes estudian alemán.</em>

n = numero total de estudiantes en la clase.

5/9 n = 15

9/5 * 5/9 * n = 15 * 9/5

n = 27

27 - 15 = 12

<em>12 estudiantes no estudian alemán.</em>
