how do you round 58.45 to the nearest tenths?

Answer 1

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.
