• could you round to the nearst thousand?
• Yes you could round to the nearest thousand. If the hundreds digit is 5 or more, then round up. If the hundreds digit is 4 or less, then round down.

Examples: 6,397 would round down to 6,000, but 3,812 would round up to 4,000.

Have a blessed, wonderful day!
• when rounding the number 345 to the nearest 100, would it be incorrect to say that 45 rounded to the nearest ten is 50 and so 350 rounded up is 400?
• Yes that would be incorrect, you only look at the number directly after the place value you are looking at. 345 is closer to 300 than to 400.
• How do you round to the Ten Millions?
• To round to any place, look at the digit to the place immediately to the right of it. Round up if the digit is 5 or more; round down if the digit is 4 or less.

So to round to the ten millions place, you would need to look at the millions digit. Example: if you need to round 386,178,093 to the ten millions place, look at the millions digit (6). Because 6 is 5 or more, round up. So the answer is 390,000,000.
• How do I round the number 960 to the nearest ten?? Can I round zeros??
• It is not necessary, because the unit is 0, and the answer remains the same.
• how do you even round to the milliones?
• I don't know.
• how can i even round with 200 to the nearest hundred?
• 200 is already rounded to the nearest hundred
• could you round to the nearst one
• who kwno what's 600+500
