Solve exercise 3 on page 27 of Math Textbook Grade 5 for Finding the Average: Finding the average of consecutive natural numbers from 1 to 9.

Guidance on solving exercise 3 on page 27 of Math Textbook Grade 5

Problem:
Find the average of consecutive natural numbers from 1 to 9.

Solution Method:
- Step 1: List consecutive natural numbers from 1 to 9: 1; 2; 3; 4; 5; 6; 7; 8; 9
- Step 2: Calculate the sum of the listed natural numbers
- Step 3: Count how many numbers from 1 to 9: There are 9 numbers
- Step 3: Find the average = Sum of the 9 natural numbers obtained: 9 (number of terms).

Answer:
The sum of consecutive natural numbers from 1 to 9 is:
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45
The average of natural numbers from 1 to 9 is:
45 : 9 = 5.
Answer: 5
