Question

В двух классах 60 человек.Сколько среди них мальчиков и сколько девочек,если девочек на 6 больше ,чем мальчиков?РЕШИТЬ ДВУМЯ СПОСОБАМИ. УРАВНЕНИЯМИ

Answer 1

х+6 +х= 60

2х+6=60

2х=60-6

2х=54

х= 54\2

х=27-мальчиков

27+6=33-девочек

Answer 2

Problem Analysis

We are given that there are 60 students in two classes, and we need to determine the number of boys and girls. We are also given that there are 6 more girls than boys. We can solve this problem using two different methods: equations and logical reasoning.

Method 1: Equations

Let's assume the number of boys in the two classes is x. Since there are 6 more girls than boys, the number of girls would be x + 6.

The total number of students in the two classes is 60, so we can write the equation:

x + (x + 6) = 60

Simplifying the equation:

2x + 6 = 60

Subtracting 6 from both sides:

2x = 54

Dividing both sides by 2:

x = 27

Therefore, there are 27 boys and 27 + 6 = 33 girls in the two classes.

Method 2: Logical Reasoning

We can also solve this problem using logical reasoning. Since there are 6 more girls than boys, we can start with an equal number of boys and girls and then distribute the additional 6 girls evenly among the two classes.

Let's assume there are 30 boys and 30 girls in the two classes. If we distribute the additional 6 girls evenly, each class would receive 3 more girls. Therefore, there would be 30 boys and 30 + 3 = 33 girls in the two classes.

Conclusion

Using both methods, we have determined that there are 27 boys and 33 girls in the two classes.
