Question

How do you round `4,278,003` to the nearest 10,000?

Answer 1

Round `4,278,003 to 4,280,000`

Explanation:

Since you are rounding to the nearest 10,000, you have to focus on the digit in the ten-thousands and thousands place in `4,278,003.`

The digit in the ten-thousands place is 7, which is the number that will either "go up" by one digit or "stay the same". To decide whether to round up or down, you have to look at the nearest digit to the right, which in this case is 8. Since 8 is higher than 5, you round 7 up to 8.
Then change all the digits to the right of the rounded 8 to 0, giving you `4,280,000.`
