Answer 1

Пусть девочек х человек, тогда мальчиков х+12 человек. а вместе х + х+12 или 88. имеем равнение
х+х+12=88
2х=88-12
2х=76
х=76/2
х=38-девочки
38+12=50-мальчики
38 девочек и 50 мальчиков

Answer 2

Calculation of the Number of Boys and Girls in School

To determine the number of boys and girls in the school, we can use the information provided. We know that there are 88 students in total, with the number of boys being 12 more than the number of girls.

Let's assume the number of girls in the school is represented by 'x'. Therefore, the number of boys can be represented as 'x + 12'.

To find the values of 'x' and 'x + 12', we can set up an equation:

x + (x + 12) = 88

Simplifying the equation:

2x + 12 = 88

Subtracting 12 from both sides:

2x = 76

Dividing both sides by 2:

x = 38

Therefore, there are 38 girls and 50 boys in the school.

Answer:

There are 38 girls and 50 boys in the school.
