c. 28 fewer
d. 36 fewer
e. 44 fewer

Option C.

Step-by-step explanation:

The number of teachers and students (kindergarten through sixth grade) totals is 510.

The ratio of students to teachers is 16:1.

16+1=17

Total number of students =

Kindergarten students make up 1/5 of the student population and fifth and sixth graders account for 1/3 of the remainder.

Kindergarten students =

5th-6th grade students =

Students in first and second grades account for 1/4 of all the students.

1st-2nd grade students =

An equal number of students in the third and fourth grades.

Let x be the number of students in class third.

3rd-4th grade students =

Total students = Kindergarten + (1st-2nd) + (3rd-4th) + (5th-6th)

Divide both sides by 2.

It means number of students in grade 3 is 68.

It means in third grade 28 fewer students than the number of students in kindergarten.

Therefore, the correct option is C.

rounding to the nearest thousandth would be 452,000
