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
3:10
If there are 125 boys and 25 girls, then the ratio of boys to girls would be 5:1.
The ratio of 8.8 to 10 is 22 : 25. The ratio is: 8.8 : 10 ⇒ 88 : 100 (multiply both sides by 10) ⇒ 22 : 25 (divide both sides by 4)
40 percent of 25 students is 10.

total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
62.5
3 to 4 cuz you would do boys first since its first in the problem
(assuming I read the question correctly) there are 25 boys and 75 girls.
Since the ratio of boys to girls is 5 to 8, the total ratio parts is 5 + 8 = 13. To find how many boys are in the class, divide the total number of girls (40) by the total parts of the ratio (13), then multiply by the number of boys parts (5). Thus, there are 15 boys in the class.
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%
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
5:7 25:30 This is because 5 goes into 25 5 times. 5 times 5=25. 7 times 5=30 Anyone disagree?
about 75% boys and 25% girls hope this helped
