1. The problem asks for the percentage of 1000 in a million. 2. The formula to find the percentage is: $$\text{Percentage} = \left(\frac{\text{Part}}{\text{Whole}}\right) \times 100$$ 3. Here, the part is 1000 and the whole is 1,000,000. 4. Substitute the values into the formula: $$\text{Percentage} = \left(\frac{1000}{1000000}\right) \times 100$$ 5. Simplify the fraction: $$\frac{1000}{1000000} = \frac{1}{1000}$$ 6. Multiply by 100 to get the percentage: $$\frac{1}{1000} \times 100 = 0.1$$ 7. Therefore, 1000 is 0.1% of a million.
