We are given the following information:
468,500 books being sold
and we are asked to round this number off to the nearest thousand.
To do this, we need to review the rules of rounding off.
When rounding off, we look at the digit to the right of the place value we are rounding off to. In this case, since we are rounding off to the nearest thousand, we look at the digit occupying the hundreds' place.
If the digit is 0, 1, 2, 3, or 4, then we round down by keeping the digit in the thousands' place and all the other digits to its left and changing the digits to its right to zero.
But when the digit is 5, 6, 7, 8, or 9, then we round up by adding 1 to the digit in the place value being rounded off to and making all other digits to its right zero.
In this case, since the digit in the hundreds' place is 5, then we need to round up. We will add one to the digit in the thousands' place and add zeros after.
So the answer is 469,000.
