According to rounding rules, how should a number ending in 5 and preceded by an odd digit be treated?

When rounding numbers, a specific rule is applied to cases where a number ends in 5 and is preceded by an odd digit. This rule states that when you encounter a situation where the last digit is 5 and the digit before it is odd, you round that number up to the next integer.

For instance, if you have the number 135, when rounding to the nearest ten, you look at the last digit (5) and the preceding digit (3, which is odd). According to the rounding rule, since 3 is odd, you would round 135 up to 140.

This rule serves to minimize bias in rounding calculations over a large dataset and ensures consistency in outcomes when rounding numbers that are precisely halfway between two integers. The choice of rounding up when dealing with odd numbers helps to balance out the tendency of rounding down when a preceding digit is even.
