Remember these rules when rounding to the nearest 100th:
Consider the following examples:
3.665 -> 3.67 2.531 -> 2.53 1.939 -> 1.94 2.335 -> 2.34 2.912 -> 2.91 .935 -> .94
Rules for rounding:
1. If the number in the thousandths column is 4 or less round down. Example:
.442 -> .44.
2. If the number in the thousandths column is 5 or more round up. Example:
.445 -> .45.
Special Case:
If you have a number like 4.995 you have to remember that it will have to round up to 5.00. Many times students are confused by this situation.
Here are a few more examples to help you out:
4.434 -> 4.43 6.719 -> 6.72 7.828 -> 7.83 1.243 -> 1.24 2.345 -> 2.35 1.335 -> 1.34
