How do you round 197.0853 to nearest tenth?

It depends on your rounding rules. The 'averaging rule' is this: 1) If the placement decimal value is 5 or higher, round up. 2) if the placement decimal value is 4 or lower, round down. For this rule, the above number will round to 197.1 If you use the 'truncation rule', you always drop ANY value at that point. For this rule, the above value will round to 197.0


How do you round 758.999?

It is rounded to 759 because the rule is when a # is greater than 5, round down and when a # is less than 5, round up.


how do you round 58.45 to the nearest tenths?

Most people would say 58.5, because most people round up if a number is followed by the number 5 or greater. However, there is an even-odd rounding rule that is used when the number to be dropped is a 5. If the number in front of the 5 is an even number, such as 58.45, then you round down, in this case to 58.4. If the number in front of the 5 is odd, you round up. For example 58.35 would round up to 58.4. You should check with your teacher about which rounding rule to use.

How do you round 35.27498 to the nearest penny?

It depends on your rounding rules. The 'averaging rule' is this: 1) If the placement decimal value is 5 or higher, round up. 2) if the placement decimal value is 4 or lower, round down. For this rule, the above number will round to 35.27 If you use the 'truncation rule', you always drop ANY value at that point. For this rule, the above value will round to 35.27 In this case, both rules give the same result. However, if the number to round was 35.27598 the different rules would give different answers. Averaging - 35.28 Truncate - 25.27
