1) The document provides information about a math class for 6th grade taught by Teacher Aneela Shaheen from 10:00-11:00 hrs. 2) The objectives are to learn the divisibility rule for 11 and check if the number 29601 is divisible by 11. 3) To check if a number is divisible by 11 using the rule, the sums of digits in odd and even positions are calculated and subtracted. If the difference is 0 or a multiple of 11, then the original number is divisible by 11.

- 3. Objectives: Divisibility rule for 11
- 4. Is 29601 divisible by 11? 29601 ÷ 11 I need to check the remainder: 1. if remainder is zero then 29601 is divisible by 11 2. If remainder is not zero, then 29601 is not divisible by 11.
- 5. Divisibility rule for 11 Find the sum of the digits at odd places and sum of the digits at even places and Subtract them. If the result is zero or the multiple of the 11 then The original number is divisible by 11.
- 6. Divisibility rule for 11 Sum Means : to perform addition Odd places means: All the digits in the position (1, 3 ,5, ...) Even places means: All the digits at even positions (2,4,6,...)
- 7. Is 29601 divisible by 11?
- 8. Step 1: Identify even and odd places
- 9. Step 1: Given number is : Number : 2 9 6 0 1 Digit position: 1 2 3 4 5 Here, positions 1 , 3 and 5 are odd position so add all the numbers on these positions. 2 and 4 represents even positions so calculate the sum of digits at even places.
- 10. Step 2: Sum of digits at odd places/ position:
- 11. Step 2: Sum of digits at odd places= 2+6+1 Sum of digits at odd places= 9
- 12. Step 3: Sum of digits at even places/ position:
- 13. Step 3: Sum of digits at even places= 9+0 Sum of digits at even places= 9
- 14. Step 4: Subtract two sum
- 15. Step 4: Subtraction of two sum= 9 – 9 Subtraction of two sum= 0
