Question

what is 391,024 rounded to the nearest hundred thousand? ?

Explanation:

Step1: Identify the digit in the hundred thousands place and the next digit.

The number is 391,024. The digit in the hundred thousands place is 3, and the next digit (ten thousands place) is 9.

Step2: Apply the rounding rule.

Since the digit in the ten thousands place (9) is greater than or equal to 5, we round up the digit in the hundred thousands place. So we increase 3 by 1 to get 4, and set all the digits to the right of the hundred thousands place to 0.

Answer:

400000
