1.1. Round 167648,489 off to the nearest hundred thousand A. 100000 B. 210000 C. 200000

To round the number 167648.489 to the nearest hundred thousand, we follow these steps: 1. Identify the hundred thousand place in the number. In 167648, the hundred thousand place is the first digit (1), which represents 100000. 2. Look at the digit immediately to the right of the hundred thousand place, which is the ten thousand place. In this case, the digit is 6. 3. According to rounding rules: - If the digit in the ten thousand place is 5 or greater, we round up. - If it is less than 5, we round down. Since the digit in the ten thousand place is 6 (which is greater than 5), we round up. 4. Rounding up from 1 (100000) gives us 2 (200000). Thus, 167648.489 rounded to the nearest hundred thousand is **200000**. The correct answer is: C. 200000
