Answer: 600 students

Step-by-step explanation:

Of the total number of sixth graders who were surveyed, 5% owned birds.

This 5% translated to 30 students.

30 students is therefore 5% of the total number of sixth graders surveyed.

Assume that number to be x:

x * 5% = 30

x = 30 / 5%

= 600 students
