385 girls
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.
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.
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.
