Answer :

Let's address both questions step-by-step:

### 7. Is 1288 a multiple of 23?

To determine if 1288 is a multiple of 23, we need to check if 1288 can be divided by 23 without leaving any remainder.

- Step 1: Divide 1288 by 23.
- Step 2: Check the remainder.

If the remainder is 0, then 1288 is a multiple of 23. In this case, 1288 divided by 23 leaves a remainder of 0. Therefore, 1288 is a multiple of 23.

### 8. Is 3030 a multiple of 36?

To determine if 3030 is a multiple of 36, we need to check if 3030 can be divided by 36 without leaving any remainder.

- Step 1: Divide 3030 by 36.
- Step 2: Check the remainder.

If the remainder is 0, then 3030 is a multiple of 36. In this instance, dividing 3030 by 36 leaves a remainder that is not 0. Therefore, 3030 is not a multiple of 36.

In summary:
- 1288 is a multiple of 23.
- 3030 is not a multiple of 36.
