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.
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.
5 to 4
Using the ratio provided, since the ratio of girls to boys is 7 to 5, the total ratio can be calculated as 7 + 5 = 12. Since there are 275 boys, the number of girls can be calculated as (7/12) * (275) = 159.375, which rounds to 159 girls.
On average, around 105 girls are born for every 106 boys. This slight natural imbalance in sex ratio at birth is a result of biological factors.
Yes, I do believe that there are more girls in the world, not too sure.
As of 2021, there are slightly more males than females on Earth. The global sex ratio is estimated to be about 101 males for every 100 females.
There are just over 7 billion people in the world, and the global sex ratio is about 1.01 male per 1 female. Therefore, we can approximate that there are about 3.52 billion men in the world and 3.49 billion women in the world.
45 boys are in the class

160 boys. 162 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.
If boys are first, I'm guessing 3 boys and 2 girls.

57 oops ! That's the boys. There are 95 girls.
6 = 2/12 = 1/6 so there are 36 in the class, 15 boys & 21 girls.
