208 девочек = 52%
х мальчиков = 48%
х = 208*48/52 = 192 мальчика
208+192 = 400 учащихся в школе

Х = 208 * 48 : 52 = 192 ( мальчика )
208 + 192 = 400 ( учеников ) всего

Answer 3

Calculation of Total Number of Students and Number of Boys in the School

To calculate the total number of students in the school and the number of boys, we can use the information provided.

Given that there are 208 girls in the school, which represents 52% of all students, we can set up the following equation:

208 = 0.52 * Total number of students

To find the total number of students, we can divide 208 by 0.52:

Total number of students = 208 / 0.52

Calculating this, we find that the total number of students in the school is 400.

To find the number of boys, we can subtract the number of girls from the total number of students:

Number of boys = Total number of students - Number of girls

Substituting the values we have:

Number of boys = 400 - 208

Calculating this, we find that the number of boys in the school is 192.

Therefore, the total number of students in the school is 400, and the number of boys is 192.
