Answer 2

32%

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}} * 100 \%`

Using the given values in above expression we get:

`(40)/(125) * 100\%\\\\= 32\%`

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