Answer 1

[0010001111]... Hello User... [1001010101]
Here's your answer...

Total students = 50
Total boys = 30
So total number of girls will be 50-30 = 20

(i) Ratio of boys to girls
= 30:20
= 3:2

(ii) Ratio of girls to total students
= 20:50
= 2:5

(iii) Ratio of boys to total students
= 30:50
= 3:5

Hello friend, this is the answer for your question....

Total no. of students in the class = 50
No. of boys = 30
No. of girls = 50-30 = 20

(i) Ratio of no. of boys to the no. of girls
= 30:20
= 3:2 (simplified the ratios)

(ii) Ration of no. of girls to the total no. of students
= 20:50
= 2:5 (simplified the ratios)

(iii) Ratio of no. of boys to the total no. of students
= 30:50
= 3:5 (simplified the ratios)
