Let's solve each question step by step and explain the reasoning.

1. Numbers which end with (0, 2, 4, 6, 8) are called ________ numbers.
Answer: *Even* numbers
✔ Explanation: Any number ending in 0, 2, 4, 6, or 8 is divisible by 2, so it's an even number.
---
2. Numbers which end with (1, 3, 5, 7, 9) are called ________ numbers.
Answer: *Odd* numbers
✔ Explanation: Numbers ending in 1, 3, 5, 7, or 9 are not divisible by 2, so they are odd.
---
3. List the odd numbers between 10 and 20.
Answer: 11, 13, 15, 17, 19
✔ Explanation: We list all numbers from 11 to 19 (since "between" means excluding 10 and 20), and pick those that are odd:
- 11 → odd
- 12 → even
- 13 → odd
- 14 → even
- 15 → odd
- 16 → even
- 17 → odd
- 18 → even
- 19 → odd
So the odd numbers:
11, 13, 15, 17, 19
---
4. Which of the following numbers (12, 3, 44, 19, 10) are even?
Answer: 12, 44, 10
✔ Explanation: Check the last digit:
- 12 → ends in 2 → even
- 3 → ends in 3 → odd
- 44 → ends in 4 → even
- 19 → ends in 9 → odd
- 10 → ends in 0 → even
So even numbers:
12, 44, 10
---
5. Which of the following numbers (21, 45, 68, 34, 87) are NOT even?
Answer: 21, 45, 87
✔ Explanation: “NOT even” means odd numbers.
Check each:
- 21 → ends in 1 → odd → NOT even
- 45 → ends in 5 → odd → NOT even
- 68 → ends in 8 → even → skip
- 34 → ends in 4 → even → skip
- 87 → ends in 7 → odd → NOT even
So numbers that are
not even:
21, 45, 87

6. Sort the numbers into the correct column.
Given numbers:
- 44, 308, 156, 63, 37, 111, 218, 25, 133, 96, 29, 70
We’ll classify each based on the last digit:
####
Odd numbers (end in 1, 3, 5, 7, 9):
- 63 → ends in 3 → odd
- 37 → ends in 7 → odd
- 111 → ends in 1 → odd
- 25 → ends in 5 → odd
- 133 → ends in 3 → odd
- 29 → ends in 9 → odd
✔ Odd:
63, 37, 111, 25, 133, 29
####
Even numbers (end in 0, 2, 4, 6, 8):
- 44 → ends in 4 → even
- 308 → ends in 8 → even
- 156 → ends in 6 → even
- 218 → ends in 8 → even
- 96 → ends in 6 → even
- 70 → ends in 0 → even
✔ Even:
44, 308, 156, 218, 96, 70
