out of 36 students in a class, 9 participate in classical dance , 12 participate in English debate and the remaining participate in singing competition. find the ratio of number of students participating in classical dance to the number of students participating in English debate , number of students participating in English debate to the number of students participating in singing competition, number of students participating in singing competition to the total number of students​

Answer 1

Answer with Step-by-step explanation:

Number of students participating in classical dance = 9

Number of students participating in English debate = 12

Number of students participating in singing competition = 36 - (9+12)

                                                                                              = 36 - 21

                                                                                              = 15

Hence, The ratio of number of students participating in classical dance to the number of students participating in English debate :  9/12 = 3/4 = 3:4                                                                                        

The ratio of number of students participating in English debate to the number of students participating in singing competition : 12/15 = 4/5 = 4:5

The ratio of number of students participating in singing competition to the total number of students​ : 15/36 = 5/12 = 5:12
