Solve problem 2 on page 27 of Math 5 Textbook: What is the average weight of each student in kilograms?

Step-by-step guide to solving problem 2 on page 27 of Math 5 Textbook

Problem Statement:
Four students Mai, Hoa, Hưng, Thịnh weigh 36 kg, 38 kg, 40 kg, and 34 kg respectively. What is the average weight of each student in kilograms?

Solution Method:
* Observations:
- Given: The weights of 4 friends Mai, Hoa, Hưng, Thịnh are 36; 38; 40; 34 respectively.
- Requirement: Find the average weight of each friend.
* Solution:
- Calculate the total weight of the 4 friends
- Calculate the average weight by dividing the total weight of the 4 friends by 4.

Answer:
The total weight of the four friends is:
36 + 38 + 40 + 34 = 148 kg.
The average weight of the four friends is:
148 : 4 = 37 kg.
Answer: 37 kg.

Frequently Asked Questions

What is the step-by-step method to find the average weight?

To find the average weight, first calculate the total weight of all students, which is 36 kg + 38 kg + 40 kg + 34 kg, resulting in 148 kg. Then, divide this total by the number of students, which is 4, giving an average weight of 37 kg.

How do I calculate the average weight of four students?

To calculate the average weight of the four students, add their individual weights together to get the total, then divide that total by 4, since there are four students involved in the calculation.

What are the weights of the students mentioned in the problem?

The weights of the students are as follows: Mai weighs 36 kg, Hoa weighs 38 kg, Hưng weighs 40 kg, and Thịnh weighs 34 kg, which are essential for calculating the average.

Why is understanding average weight important for students?

Understanding average weight helps students grasp fundamental mathematical concepts, enhances their problem-solving skills, and provides practical applications in real-life scenarios like health and fitness assessments.
