Question

The student body at a High School was surveyed about sports participation. The table below shows the data by grade level.

Answer 1

9% are in the 9th grade and do not play a sport.

There are 55 students in the 9th grade that do not play a sport.  This is out of a total of 612 students:
55/612 = 0.0899 = 8.99% ≈ 9%

Answer 2

Answer:

9%

Step-by-step explanation:

There are 612 students at all and 55 of them are in the 9th grade and don't play a sport. Therefore,

612 students - 100%,

55 students - x%.

Mathematically, you can write a proportion:

$\dfrac{612}{55}=\dfrac{100}{x},\\ \\x=\dfrac{55\cdot 100}{612}=\dfrac{5500}{612}\approx 9\%.$
