Look at the last digit. If it is a zero, it does not need to be rounded.
4870 does not change.
If it is 1, 2, 3 or 4, it is rounded down, replacing that digit with a zero.
5214 becomes 5210.
If it is 5, 6, 7, 8 or 9, it is rounded up, so the digit becomes zero and the digit beside it is incremented by one.
8176 becomes 8180.
To the nearest 'ten' as you said, it would be: 10 To the nearest 'tenth," it would be: 8.1 To round a number, look at the number right after the number you want it to stop at. If that number is greater than 5, then you round up one digit. If it is 4 or below, the digit stays the same.
Your question is obviously missing something. I'm pretty sure that you meant to ask what is the greatest 2 digit number that is still a 2 digit number when rounded to the nearest 10. The answer could be 94 or 95, depending upon how you round 95. 95 could be rounded to 90 or to 100, since it is exactly half way between 90 and 100. There is no hard and fast rule regarding how you should round a number ending in 5.
Since the last digit is over 5, than you round up to 730.
It depends on how precise you want to be. To round to the nearest tenth, you would observe that the digit n the thousands position is 1, which is closer to 0 than to 10 so you would round down to get 35.7 To round to the nearest whole number, you would observe that the digit n the tenths position is 7, which is closer to 10 than to 0 so you would round up to get 36. To round to the nearest ten, you would observe that the digit n the ones position is 5 (and that there is a bit more in the decimal spots), which is closer to 10 than to 0 so you would round up to get 40. To round to the nearest hundred, you would observe that the digit n the tens position is 3, which is closer to 0 than to 10 so you would round down to get 0.
As the final digit is a 9 we round up so the answer is 43180.
To the nearest 'ten' as you said, it would be: 10 To the nearest 'tenth," it would be: 8.1 To round a number, look at the number right after the number you want it to stop at. If that number is greater than 5, then you round up one digit. If it is 4 or below, the digit stays the same.
you round up on a number if the last digit is 5 thru 9 you round down if the last digit is 4 thru 1 therefore 31 rounded to the nearest ten is 30
45420
When rounding a number to the nearest whole number, you look at the digit immediately to the right of the decimal point. In this case, the digit is 2. Since 2 is less than 5, you would round down. Therefore, 10.245 rounded to the nearest whole number is 10.
320
Round 12.7 to the nearest whole number would be 13. When rounding a number, you look at the digit immediately to the right of the place value you are rounding to. If that digit is 5 or greater, you round up; if it is less than 5, you round down. In this case, since the digit to the right of the tenths place is 7, which is 5 or greater, you round up to 13.
To round 29.56 to the nearest 10, we look at the digit in the tens place, which is 2. Since the digit to the right of it is 9, we round up. Therefore, 29.56 rounded to the nearest 10 is 30.
590
Look at the digit in the ones position. That is the 9. A 9 will round the number up, so 89 will round up to 90.
The number 3400 is already rounded to the nearest 10.
To round 1395 to the nearest 10, we look at the digit in the tens place, which is 9. Since 9 is greater than or equal to 5, we round up. Therefore, 1395 rounded to the nearest 10 is 1400.
