a class of 25 students has 10 boys. Three boys have braces and 4 girls have braces..what is the ratio of boys with braces to boys in class
If there are 125 boys and 25 girls, then the ratio of boys to girls would be 5:1.
total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
25 If the ratio is 5 boys to 8 girls, there are 25 girls and 15 boys in the class. To solve for girls, multiply 40 x 5/8. Then subtract the girls from 40 to find how many boys.
3 to 4 cuz you would do boys first since its first in the problem
The probability of choosing 2 girls at random from group of 25 students of which10 are girls and 15 are boys is:P( 2 girls) = (10/25)∙(9/24) = 3/20 = 0.15 = 15%
75 girls and 25 boys You need to divide 100 by 4 (3 lots of girls and 1 lot of boys) then multiply that answer by 3 to work out the number of boys. It's a simple ratio problem 100 split in the ratio of 3:1
the trick for working ratio and proportions out is to,eg, say if there 5 girls in a class and the ratio of how many boys was 5:1 there will be 25 boys because you simply have to do 5x5=25 then simply times it by one .i think
about 75% boys and 25% girls hope this helped
5:7 25:30 This is because 5 goes into 25 5 times. 5 times 5=25. 7 times 5=30 Anyone disagree?
