Answer:
23,421 to the nearest thousand will be 23,000.
23,421 to the nearest ten thousand will be 20,000.
Step-by-step explanation:
We have to round 23,421 to the nearest thousand and ten thousand.
23,421 to the nearest thousand will be 23,000.
3000 because, the hundreds digit is 4 which is less than 4, so it will be rounded to 0.
23,421 to the nearest ten thousand will be 20,000.
Here, the thousand place is 3 which is less than 5 so, the numbers are rounded to 0.
