round to 66,000 when rounded to nearest thousand and 66,400 when rouned to the nearest hundred? what is the answer?

many possible answers, anywhere from

66,351
66,449

anything less than 66,500 rounds down to 66,000
But you need to also round to 66,400, so it must end in 350-450

To round a number to the nearest thousand, we look at the hundreds place. If the digit in the hundreds place is 5 or greater, we round up to the next thousand. If the digit in the hundreds place is less than 5, we round down to the current thousand.

In this case, the number is 66,000. Looking at the hundreds place, it is 0. Since 0 is less than 5, we round down to the current thousand, which is 66,000.

To round a number to the nearest hundred, we look at the tens place. If the digit in the tens place is 5 or greater, we round up to the next hundred. If the digit in the tens place is less than 5, we round down to the current hundred.
In this case, the number is 66,400. Looking at the tens place, it is 4. Since 4 is less than 5, we round down to the current hundred, which is 66,400.

Therefore, the answer is: 66,000 when rounded to the nearest thousand and 66,400 when rounded to the nearest hundred.
