Solve Exercise 3 on Page 28 of Math 5 Workbook Practice: What is the average height measurement of each student in centimeters?

Guidelines for solving Exercise 3 on Page 28 of Math 5 Workbook Practice

Problem Statement:

Average the height measurements of 5 students in Class Four: 138 cm, 132 cm, 130 cm, 136 cm, 134 cm.

Solution Method:
* Problem Analysis:
- Given: Height measurements of 5 students are: 138; 132; 130; 136; 134 (cm)
- Required: Calculate the average height measurement of each student.
* Procedure:
- Calculate the total height of 5 students by adding all known measurements together
- Calculate the average height measurement of each student by: Taking the total height : 5 (students).

Answer:

Total height of 5 students is: 138 + 132 + 130 + 136 + 134 = 670 cm.

The average height measurement of each student is: 670 : 5 = 134 cm

Answer: 134 cm

Frequently Asked Questions

What steps are involved in calculating average height measurements of students?

To calculate the average height of students, first sum their height measurements. For example, if the heights are 138 cm, 132 cm, 130 cm, 136 cm, and 134 cm, add these values to get 670 cm. Then, divide the total by the number of students, which in this case is 5. The average height is therefore 134 cm.
