Question

How do you estimate `8,733 + 7,423 + 13,756` by first rounding each number to the nearest thousand?

Answer 1

The estimate would be `30,000`.

Explanation:

Since you first are rounding each number to the nearest thousand, that is your first step.

1) Take `8,733` first:

Hundreds place: `7`

`color(red)(NOTE)`

Remember, if the number in the hundreds place is`<= 4`, then we must round the number down. If the number is`>= 5`, then we must round the number up

Since the hundreds place in `8,733` is `7`, this means that the number is rounded up.

`color(red)(END NOTE)`

Therefore, `8,733` becomes `9,000`.

2) Now `7,423`:

Hundreds place: `4`

Therefore, `7,423` becomes `7,000`.

3) Finally, `13,756`:

Hundreds place: `7`

Therefore, `13,756` becomes `14,000`.

4) Now all you have to do is add up all of your estimated values:

`9,000 + 7,000 + 14,000`

`= 16,000 + 14,000`

`= 30,000`
