1. The problem is to convert 89 millimeters (mm) to meters (m) correctly. 2. Recall the conversion factor: 1 meter = 1000 millimeters. 3. To convert millimeters to meters, divide the number of millimeters by 1000. 4. Calculate: $$89 \text{ mm} = \frac{89}{1000} \text{ m} = 0.089 \text{ m}$$ 5. Therefore, 89 mm equals 0.089 m, not 0.89 m. 6. The original statement 89 mm = 0.89 m is incorrect because it is off by a factor of 10.
