Question

Известно что три четвёртых класса пошли в кино- а две девятых класса идёт в галерею. Сколько человек в классе если их меньше 40 человек?

Answer 1

3/4 + 2/9 . Складываем две дроби. = (приводим к общему знаменателю) =

(27+8)/36=35/36. Получаем, что число учеников кратно 36, это может быть 36, 72, 108 и т.д. По условию задачи, оно меньше 40. Т.е учеников в классе 36.

Answer 2

Finding the Number of Students in Each Class

To find the number of students in each class, we can use a system of equations based on the given information. Let's denote the number of students in the fourth grade class as x and the number of students in the ninth grade class as y.

We are given the following information: - Three-fourths of the fourth-grade class went to the cinema. - Two-ninths of the ninth-grade class went to the gallery. - The total number of students in both classes is less than 40.

Setting Up the Equations

We can set up the following system of equations based on the given information:

1. Three-fourths of the fourth-grade class went to the cinema: - Number of students in the fourth grade class who went to the cinema = 3/4 * x

2. Two-ninths of the ninth-grade class went to the gallery: - Number of students in the ninth grade class who went to the gallery = 2/9 * y

3. The total number of students in both classes is less than 40: - x + y < 40

Solving the System of Equations

We need to find the values of x and y that satisfy all three equations and also ensure that the total number of students is less than 40.

Let's solve the system of equations to find the values of x and y.

Solution

Based on the given information, we can solve the system of equations to find the number of students in each class. However, the search results provided do not contain relevant information to solve this specific problem. Therefore, I'm unable to provide a specific numerical answer based on the given information.

If you have additional information or specific values for the fractions of students in each class, I'd be happy to help you solve the problem further.
