Oh, dude, you're hitting me with some math vibes, I see. So, in a class of 29 students with 13 boys, the ratio of boys to girls is 13:16. Yeah, that's right, just some simple division and you got your answer. Like, ratios, man, they're everywhere, just chilling and waiting for us to calculate them.
If the boy to girl ratio in the class is 3:5, this means that for every 3 boys, there are 5 girls. To find the number of boys in the class, you need to divide the total number of students by the total parts of the ratio (3+5=8) to get the value of each part. Then multiply this value by the number of parts representing boys (3) to find the number of boys. Therefore, in a class of 24 students, there would be 9 boys (24/8=3, 3x3=9).
If the ratio of boys to girls is 12 to 3, then the total ratio is 12 + 3 = 15. To find how many girls are in the class, we divide the number of girls by the total ratio, 24 / 15 = 1.6. This means there are approximately 1.6 girls in the class. However, since we can't have a fraction of a girl, we can conclude that there are 2 girls in the class.
Ratios are good for comparing two quantities. Like in a classroom, the ratio of girls to boys, for example. Say the class has 40 students, and 22 of them are girls, so this is 22/40 = 55% of the class. But the ratio is comparing the girls to the boys, not the entire class. So if there are 55% girls, then 100% - 55% = 45% boys. Now the ratio can be made of 55 : 45 girl to boy ratio. This can be simplified to a 11:9 ratio.
There would be 6 boy students and 18 girl students in the class.
According to the CIA World Factbook, the 2014 ratio is 1.07 boys per girl.
If there are 24 girls in a class of 50 and we assume the remaining students are boys, then there are 26 boys and the ratio of boys to girls is 26boys/24girls = 13/12=1.08333 boys for each girl.
If the boy to girl ratio in the class is 3:5, this means that for every 3 boys, there are 5 girls. To find the number of boys in the class, you need to divide the total number of students by the total parts of the ratio (3+5=8) to get the value of each part.

The probability is 15/25 = 3/5
number of boys = ratio of boys x total strength / total ratio = 5 x 27/9 = 5 x 3 = 15 number of girls = ratio of girls x total strength / total ratio = 4 x 27/9 = 4 x 3 = 12 verification: 15 + 12 = 27
There were 49 boys
146 students.... 84 boys. Meaning there are 84 boys and 62 girls. (146-84=62) 84 divided by 62 is 1.355. Meaning 1.355 boys to every 1 girl.
The probability is the number of girls divided by the number of students, so 12/22, or 6/11
The probability is 15/25 = 3/5
