To determine the best answer for the question of rounding 1,112,433 to the nearest ten thousand, let's follow these detailed steps:
1. Identify the digit in the ten thousand place:
- In the number 1,112,433, the ten thousand place is the second digit from the right after the million, which is 1 (in the tens place of the number 11).
2. Look at the digit immediately to the right of the ten thousand place:
- The digit immediately to the right of the ten thousand place is 2.
3. Decide whether to round up or down:
- The rule for rounding is that if the digit to the right is 5 or greater, we round up. If it is less than 5, we round down.
- Here, the digit 2 is less than 5, so we round down. This means the digit in the ten thousand place (1) remains the same, and all the digits to the right become zeros.
4. Form the rounded number:
- Keeping the ten thousand place digit while turning all the following digits to zeros, we get 1,110,000.
Comparing this result with the choices given:
- A. 1,100,000
- B. 1,200,000
- C. 1,120,000
- D. 1,110,000
The best answer is:
- D. 1,110,000
So, the number 1,112,433 rounded to the nearest ten thousand is 1,110,000.
