Answer 1

5+3=8
83-8=75
75:3=25
25-5=20 (уч) в 1"б"
25+3=28(уч) в 1"а"
20+28=48(уч) 
83-48=35(уч) в 1"в"

Answer 2

Problem Analysis

We are given information about the number of students in three different classes: 1 "a" class, 1 "b" class, and 1 "v" class. We need to determine the number of students in the "v" class.

Given Information

- In the 1 "b" class, there are 5 fewer students than in the 1 "a" class. - In the 1 "b" class, there are 3 more students than in the 1 "v" class.

Solution

Let's assume the number of students in the 1 "a" class is A, the number of students in the 1 "b" class is B, and the number of students in the 1 "v" class is V.

From the given information, we can write the following equations: 1. B = A - 5 (There are 5 fewer students in the 1 "b" class than in the 1 "a" class). 2. B = V + 3 (There are 3 more students in the 1 "b" class than in the 1 "v" class).

To find the number of students in the 1 "v" class, we can substitute the value of B from equation 2 into equation 1: V + 3 = A - 5

Simplifying the equation, we get: V = A - 8

Therefore, the number of students in the 1 "v" class is A - 8.

Answer

The number of students in the 1 "v" class is A - 8.

Note: To determine the exact number of students in the 1 "v" class, we need to know the number of students in the 1 "a" class (A).
