Answer 1

Answer:

given,

no of boys in a school = 420

no of girls in a school = 180

total number of students in the school = 420+180 = 600

ratio of no of girls to no of boys = 180: 420 = 3:7

ratio of no of girls to toatal no of students = 180:600 = 3:10

ratio of no of boys to total no of students = 420:600 = 7:10

Answer 2

Answer:

Step-by-step explanation:

Total boys = 420

Total girls = 180

Total number of students in whole school =420+180=600 students

Now,

(1) ratio of girls to boys = 180/420=3:7

(2) girls to TOTAL STUDENTS of school = 180 / 600 = 3:10

(3) boys to total number of students of school =420/600 = 7:10
