B. 1 kg 12 gm = 1.012 kg
C. 10 m 10 cm = 1010 cm
D. `(23)/(100) =2.30`

Answer

To determine which of the following statements is not correct, we will analyze each option step by step.

### Step 1: Analyze the first option
**Statement:** 1 mm equals to 1/10 of 1 centimeter.

- We know that 1 centimeter (cm) is equal to 10 millimeters (mm).
- Therefore, 1 mm = 1/10 cm is indeed correct.

**Conclusion:** This statement is correct.

### Step 2: Analyze the second option
**Statement:** 12 grams can be written as 12 divided by 1000 kg.

- We know that 1 kilogram (kg) is equal to 1000 grams (g).
- To convert grams to kilograms, we divide by 1000.
- Thus, 12 grams = 12/1000 kg = 0.012 kg.

**Conclusion:** This statement is correct.

### Step 3: Analyze the third option
**Statement:** 10 meters can be written as 1.010 centimeters.

- We know that 1 meter = 100 centimeters.
- Therefore, 10 meters = 10 * 100 cm = 1000 cm.
- The statement claims that 10 meters = 1.010 cm, which is incorrect.

**Conclusion:** This statement is incorrect.

### Step 4: Analyze the fourth option
**Statement:** 23 divided by 100 equals 2.30.

- Performing the division: 23 ÷ 100 = 0.23.
- The statement claims that this equals 2.30, which is incorrect.

**Conclusion:** This statement is also incorrect.

### Final Conclusion
The question asks which of the following is not correct. From our analysis:
- The third option (10 meters = 1.010 centimeters) is incorrect.
- The fourth option (23 divided by 100 equals 2.30) is also incorrect.

However, since the question asks for a single incorrect statement, we can conclude that the third option is the most clearly incorrect based on the context of the question.

### Answer: The third option is not correct.
