11. In a class of 150 students 80 are girls. Find the following
(a) Ratio of boys to girls
(c) Ratio of boys to total students
(b) Ratio of girls to total Student​

Answer 1

Step-by-step explanation:

So,

number of boys+ number of girls= total number of students

i.e, boys+80 = 150

boys= 150-80 =70

(a) ratio= 70:80

=> 7:8

(b) ratio= 70:150

=> 7:15

(c) ratio= 80:150

=> 8:15
