Answer:
5,000
Explanation:
In order to round, check to see if the next digit over to the right is greater than or equal to 5, if so round it up by 1 whole number. Once, we do that, make all the numbers to the right of the number you are rounding 0. If not (less than 5), keep the number the same and make the rest of the digits on the right side 0.
In this case, we are focusing on the thousands place. The thousands place is 4 digits left of the decimal point.
So, the number we are looking at is 4.
Let's look at the next digit over, 8.
8 is greater than 5 so we must round 4 up one whole.
4 + 1 = 5
The new rounded thousands place is 5.
Now let's change all the numbers to the right of 4 including 8 into 0 and change 4 to 5.
It's now rounded to:
5,000
