Answer 2

Answer:

32%

Step-by-step explanation:

The given table in the correct format is attached in the image below. We need to tell what percentage of students from the grades 9 - 10 like rap music.

Total number of students in grades 9 - 10 = 125

Number of students in grades 9 - 10 who like rap music = 40

Percentage of students in grades 9 - 10 who like the rap music will be calculated as:

$\frac{\text{Number of students in grades 9-10 who like rap music}}{\text{Total number of students in grades 9-10}} \times 100 \%$

Using the given values in above expression we get:

$\frac{40}{125} \times 100\%\\\\= 32\%$

This means 32% of the students in grades 9 - 10 like rap music
