Answer:

If 2 out of every 8 students in a class of 32 walk to school, you can use the proportion:

2/8 = x/32

Where x is the number of students in the class of 32 that walk to school.

To find x, you can cross-multiply and divide:

32 * 2 = 8x

x = 32 * 2 / 8

x = 8

So 8 out of 32 students in the class walk to school.
