Answer 1

Answer:

A. TELEVISION= 100/360= 5/18

MUSIC= 90/360= 1/4

B. 18+6+28+20= 72

Step-by-step explanation:

A. As we know that the total no. of students are 360(by adding all the votes), we can calculate the answers. The rest of the process is given above.

B. If only 18 students choose music, then we can calculate that everyone student is giving 5 votes on his behalf ( 90÷18= 5) .

So if we divide all the votes by 5 and add them, then we will get the answer, which is given above.
