If the decimal point on a number is less than 0.5 then round the number down, for example 12.49999 rounds to 12 with zero decimal places.

If the decimal point on a number is equal to or greater than 0.5 then round the number up, for example 12.500000 rounds to 13 with zero decimal places.

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.
