What answer did you get when you tested 2,385 for divisibility?
what
2 is not divisible by 10
Nope.
Is 2,385 divisible by any of the numbers?

You don't know how to divide, do you?
2,385 / 2= 1192.5
Right -- so 2385 is not divisible by 2 or 10. What about 3 and 5?
it is divisible by 3, 5
Right.
i think i got it now
To test each number for divisibility, we need to check if they can be divided evenly by 2, 3, 5, and 10. Let's go through each number one by one:
1. For 11:
- To test divisibility by 2, we check if the number is even. 11 is odd, so it is not divisible by 2.
- To test divisibility by 3, we can add up the digits of the number and check if the sum is divisible by 3. However, in this case, we don't need to do that since 11 is not divisible by 3.
- To test divisibility by 5, we check if the number ends in 0 or 5. Since 11 does not have a 0 or 5 at the end, it is not divisible by 5.
- To test divisibility by 10, we only need to check if the number ends in 0. As 11 does not end in 0, it is not divisible by 10.
2. For 13:
- Following the same process, we find that 13 is not divisible by 2, 3, 5, or 10.
3. For 15:
- 15 is divisible by 5 since it ends in 5.
- However, 15 is not divisible by 2, 3, or 10.
4. For 17:
- 17 is not divisible by 2, 3, 5, or 10.
5. For 19:
- 19 is not divisible by 2, 3, 5, or 10.
6. For 21:
- 21 is divisible by 3 since the sum of its digits (2 + 1 = 3) is divisible by 3.
- However, 21 is not divisible by 2, 5, or 10.
Here are the results:
- 11 is not divisible by 2, 3, 5, or 10.
- 13 is not divisible by 2, 3, 5, or 10.
- 15 is divisible by 5, but not divisible by 2, 3, or 10.
- 17 is not divisible by 2, 3, 5, or 10.
- 19 is not divisible by 2, 3, 5, or 10.
- 21 is divisible by 3, but not divisible by 2, 5, or 10.
