Question

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

Answer 1

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:

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

Answer 2

A percentage is a way to describe a part of a whole. The percentage of students who are in 9th standard and do not play sports is 9% of the total student.

What are Percentages?

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

The total number of students in the school is 612, while the number of students who are in 9th standard and do not play sports is 55. Therefore, the percentage of students can be written as,

$\rm Percentage = \dfrac{\text{Number of Students who are in 9th standards}}{\text{Total number of students}} \times 100\%$

$\rm Percentages = \dfrac{55}{612} \times 100\% = 8.986\%\approx 9\%$

Hence, the percentage of students who are in 9th standard and do not play sports is 9% of the total student.
