Round 89,678 to the nearest hundred thousand

The nearest 100,000 of 89,678 would be 100,000.

Step-by-step explanation:

For me to simply put this, ignore the digits behind the commas.

You'll have 89, and imagine you have to get it to the nearest 100.

So when rounding / estimating, if the digit you're talking about is above 5, you round up. If it is below 5, you round down.

Since you have 89, you'd round up to a 100 because 89 is over 50.

Therefore you'd have 100,000 if you're rounding 89,678 to the nearest hundred thousand.
