Let's solve this
Divisibility Rules Sheet 1 step by step.
We are asked to determine whether each number in the list is divisible by
1,
5, and
10. We’ll use basic divisibility rules:
---
🔹 Divisibility Rules:
-
Divisible by 1:
All whole numbers are divisible by 1.
→ So, for every number, the answer is
yes.
-
Divisible by 5: A number is divisible by 5 if its
last digit is 0 or 5.
-
Divisible by 10: A number is divisible by 10 if its
last digit is 0.
---
Now, let’s go through each number one by one.
| NUMBER | DIVISIBLE BY 1 | DIVISIBLE BY 5 | DIVISIBLE BY 10 |
|--------|----------------|----------------|------------------|
| 22 | yes | no | no |
| 35 | yes | yes | no |
| 80 | yes | yes | yes |
| 77 | yes | no | no |
| 45 | yes | yes | no |
| 120 | yes | yes | yes |
| 93 | yes | no | no |
| 184 | yes | no | no |
| 150 | yes | yes | yes |
| 263 | yes | no | no |
| 300 | yes | yes | yes |
| 195 | yes | yes | no |
| 324 | yes | no | no |
| 170 | yes | yes | yes |
| 416 | yes | no | no |
| 753 | yes | no | no |
| 465 | yes | yes | no |
| 390 | yes | yes | yes |
| 1425 | yes | yes | no |
| 1107 | yes | no | no |
| 3130 | yes | yes | yes |
| 4108 | yes | no | no |
| 2205 | yes | yes | no |

✔ Explanation of Each Entry:
-
Divisible by 1: Always
yes.
-
Divisible by 5: Check last digit = 0 or 5?
-
Divisible by 10: Check last digit = 0?

🟩 Challenge Question:
> Can you find a number between 163 and 184 which is divisible by 1, 5, and 10?
Let’s think:
- All numbers are divisible by 1 → we just need one divisible by
5 and 10.
- But to be divisible by
10, it must end in
0.
- Numbers between 163 and 184 ending in 0:
→ 170
Check:
- 170 ÷ 1 = 170 → ✔️
- 170 ÷ 5 = 34 → ✔️
- 170 ÷ 10 = 17 → ✔️
✔ So,
170 is the number.

✔ Final Answer:
####
Challenge Answer: 170
