Answer:
(a) 3:7
(b)27:1
(c)61:1
(d)70%
Step-by-step explanation:
Total number of students = 180
Percentage of girls = 70%
Number of girls = 126
Number of boys = 54
Total number of teachers = 10
Number of female teachers = 8
Number of male teachers = 2
According to the problem,
(a) Ratio of the number of boys to girls = 54:126
= 3:7
(b) Ratio of the number of boys to the number of male teachers = 54:2
= 27:1
(c) Ratio of the number of girls to the number of male teachers = 126:2
= 61:1
(d) Percentage of number of female teachers if the total number of the students = (126/180) * 100
