To find the number of boys in the class, we first need to determine the total number of students. Since the ratio of boys to girls is 5 to 8, the total parts of the ratio is 5 + 8 = 13. If there are 40 girls in the class, we can calculate the total number of students as 40 girls / 8 girls per part = 5 parts. So, the total number of students is 5 parts * 13 total parts = 65 students. To find the number of boys, we can calculate 65 total students - 40 girls = 25 boys in the class.
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.
Genetic survival depends on an average of a few more females to males in the world.
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.
To determine the number of boys and girls in the class given a ratio of 32, we need more information. A ratio typically compares two quantities, such as boys to girls (e.g., 3:2). Without specific numbers or a context for what the ratio represents, we cannot ascertain the actual counts of boys and girls. Please provide additional details for a precise answer.
