What is 351,871 +101,949 but rounded to the hundred thousand?

500,000

Step-by-step explanation:

We know that this is not greater than 500,000 but also greater than 450,000 just by looking at it -- 351,871 is greater than 350,000 but less than 375,000, and 101,949 is greater than 100,000 but less than 125,000. Thus, as we want to round to the nearest hundred thousand, we want to count to the sixth digit to the left of the decimal place. Since there is no decimal place, we can place it at the end, like so:

351,871.00

Thus, we can add these two numbers up, and since we know that the answer is greater than 450,000 and less than 500,000, we can take the number to the right of the hundred thousand place; if it is 5 or greater, it will round up, and if not, it will round down. Since anything between 450,000 and 500,000 has a ten thousand value of 5 or higher, we can round the hundred thousand place up, in this case to 500,000
