Explanation:
Detailed explanation-1: -If the ratio of boys to girls is 4 : 3, that means for every 4 boys, there are 3 girls. If we divide 35 students by 7 (the total of 4 + 3) then 7x 5 = 35 total. 4 x 5 = 20 (boys) and 3 x 5 = 15 (girls) which equals the total of 35 students.
Detailed explanation-2: -In the classroom example, many other ratios can be made. The number of boys out of the total number of students is 10/25. The number of girls out of the total number of students is 15/25. And 15/10 is the ratio of the number of girls to the number of boys.
Detailed explanation-3: -The two numbers when 35 is divided into 3:4 will be 15 and 20 respectively.
Detailed explanation-4: -Required ratio = 30 : 20 = 3 : 2.
