How do you round 999999 to the nearest ten or nearest hundred and nearest ten thousand?

Answer 1

To round a number to a power of 10, you look at the digit in the place value column following the digit to which you wish to round; if it is 0-4 the number rounds down otherwise it rounds up. To round to the nearest 10, you look at the units digit; to the neatest 100, you look at the 10s digit, to the nearest 10,000 you look at the 1,000s digit.

In every case the digit is a 9, so the number rounds up (each time) to 1,000,000.

Answer 2

To round 999999 to the nearest ten, we look at the digit in the tens place, which is 9. Since 9 is greater than or equal to 5, we round up to the next ten, giving us 1000000. To round to the nearest hundred, we look at the digit in the hundreds place, which is 9. Again, since 9 is greater than or equal to 5, we round up to the next hundred, giving us 1000000. To round to the nearest ten thousand, we look at the digit in the ten thousands place, which is 9. Since 9 is greater than or equal to 5, we round up to the next ten thousand, giving us 1000000.
