Round 345,047 to the nearest thousand ten thousand hundred thousand

300,000

Step-by-step explanation:

the ten hundred thousands place would be

100,000

therefore the nearest ten hundred thousand would be

300,000

because the 345,047 isn't a high enough digit to be 5+ and make the nearest thousand 400,000 and not 300,000

If that doesn't help, think of it like this...

Anything before the place is what determines if the number will be higher or lower.

45 is lower than 50 and 50+ is the passing number to make the number 400,000.

Tip: when your rounding numbers the only numbers that stay the same and don't turn into 0's is like the 3 in "345,047" but the "45,047" part turns into 0's is because those aren't needed and because you rounded it, it's like it takes those numbers to make what you rounded to higher or lower.

so if you look at it like that the answer is 300,000.
