Here are the rules for rounding:
For example, if a problem ask you round to the nearest tens and they gave you this number to solve: 8,951; you round the 5 because it's in the tens place. To round it, you'll need the digit before 5, which is 1. If the digit before the chosen place value is 0-4, then the chosen value stays the same. If it's 5-9, then the chosen value gains a value. In this case, 1 is in 0-4, so that means 5 stays the same, but ALL the digits that are right of 5 becomes 0, so 1 turns into a 0, and the answer is 8,950.

If you are rounding to 100ths it is 1.73 . If you are rounding to 10ths it is 1.7 . If you are rounding to integers it is 2 .
The process of rounding is the same no matter what place you're rounding to.
In a multi-step calculation, it's generally best to avoid rounding until the final result to maintain accuracy. If rounding is necessary at intermediate steps, limit it to one or two decimal places, depending on the precision required for the final answer. Ultimately, the goal is to keep as much precision as possible throughout the calculation to minimize rounding errors.
-- If rounding to the nearest 300, then 749 is. -- If rounding to the nearest 200, then 699 is. -- If rounding to the nearest 150, then 674 is. -- If rounding to the nearest hundred, then 649 is. -- If rounding to the nearest twenty, then 609 is. -- If rounding to the nearest ten, then 604 is.
