| 00:0-1 | To round 0.8005 to the underlying place value position . | |
| 00:06 | First find the digit in the rounding place which in | |
| 00:09 | this case is the zero in the thousands place . | |
| 00:13 | Next look at the digit to the right of the | |
| 00:16 | rounding place which is five . Remember that ? The | |
| 00:19 | rules of rounding tell us that if the digit to | |
| 00:21 | the right of the rounding place is less than five | |
| 00:24 | , we round down and if the digit to the | |
| 00:27 | right of the rounding place is greater than or equal | |
| 00:29 | to five , we round up . So in this | |
| 00:32 | case since the digit to the right of the rounding | |
| 00:34 | place , five is greater than or equal to five | |
| 00:38 | . We round up this means that we add one | |
| 00:41 | to the digit in the rounding place , so zero | |
| 00:44 | becomes one and we change all digits to the right | |
| 00:47 | of the rounding place to zero , So we have | |
| 00:51 | 0.8010 . Finally it's important to understand that when rounding | |
| 00:58 | decimals we can drop any zeros to the right of | |
| 01:02 | the decimal point as long as they are also to | |
| 01:04 | the right of the rounding place . So 0.8010 can | |
| 01:10 | be written as 0.801 , Which means that 0.8005 rounded | |
| 01:19 | to the nearest 1000th , is 0.801 . |
