Answer:27.78% ; Twi; 1/3
Step-by-step explanation:
Given the data :
Language - - - - - - - Number of students
Nzema - - - - - - - - - - - 5
Ga - - - - - - - - - - - - - - - 20
Twi - - - - - - - - - - - - - - - 30
Ewe - - - - - - - - - - - - - - - 25
Fante - - - - - - - - - - - - - - 10
1.) To prepare pie chart:
Total number of students :
(5 + 20 + 30 + 25 + 10) = 90 students
Nzema: (5/90) × 360 = 20
Ga : (20/90) × 360 = 79.99 = 80
Twi : (30/90) × 360 = 119.99 = 120
Ewe : (25/90) × 360 = 79.99 = 100
Fante : (10/90) × 360 = 39.99 = 40
Total = 360
Pie chart is attached in the picture below
2)Percentage students that speak Ewe = (25/90) * 100 = 27.78%
Or (100/360) * 100 = 27.78%
3.) Modal language : This is the language spoken by majority of the students = Twi
4.) Fraction of student that speak either GA or Fante :
(GA or Fante) = (20 + 10) / 90 = 30/90 = 1/3
