454,493 rounded to the nearest thousand

454,000

Step-by-step explanation: To round 454,493 to the nearest thousand, we first find the digit in the rounding place which in this case is the 4 in the thousands place.

Next, we look at the digit to the right of the 4 which is 4.

According to the rules of rounding, since the digit to the right of the rounding place is less than 5, we round down. If it was greater than or equal to 5, we would round up but we need to round down.

So the 4 in the rounding place stays the same and all numbers to the right of the 4 become 0. So 454,493 rounded to the nearest thousand is 454,000.
