Answer 1

Answer:

i) Percentage of students absent = 20%

ii) Percentage of students present = 80 %

Step-by-step explanation:

Total number of students in the class = 45 students

Number of students absent in the class = 9 students

i) Percentage of students absent =((number of students absent) / (total number                                                                                                                                          

                                                               of students)) × 100

                                                  = (9/45) × 100 = 20 %

ii) Percentage of students present =((number of students present) / (total

                                                              number of students ))  × 100

                                                                                                                                       

                                                   = ((45 - 9)/45) × 100 = 80 %
