What is 7,491,001 rounded to the nearest hundrer thousand

Answers

Answer:

7,491,001 --> 7,500,000

Step-by-step explanation:

This is because rounding happens like this:

The rounding rule is: 5 and above rounds up, and 4 and under rounds down.

Here is a little rhyme for the rule: 5 and above rounds up like a dove. 4 and below, get down low!

7,491,001

--> you want to round the underlined digit. You round using the next digit to the right. The next digit over is the 9. Remember our rounding rule. Since 9 is above 5, the 4 would round up. Note - the digits after the rounded number always become zeros, even if you round up or down. So our new number is 7,500,000.
