9 boys

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.

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

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.

There were 49 boys

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
