Answer 1

Answer: C

because 28 students who are in 12th grade that play 2 or more sports divided by the total 612 students to make a ratio

Explanation:

Answer 2

From the first line of this table you can see that 55 students in the 9th grade don't play a sport. (This is the part number.)

Total amount of students is 612 (so, the whole number is 612).

`(part)/(whole) = (55)/(612) \approx 0.09 \\ 0.09= (9)/(100)=9\%`.
Answer: nearly 9% of the student body are in the 9th grade and don't play a sport.
