Question: 1 / 400

When rounding ampacity values, to what should the value of 20.45 be rounded?

20 A

When rounding ampacity values, the standard procedure is to round to the nearest whole number. In the case of the value 20.45, you focus on the first digit after the decimal point, which is 4. According to conventional rounding rules, when this digit is less than 5, you round down. Since 4 is less than 5, you round the value down to 20.

Therefore, the final rounded value from 20.45 becomes 20 A. This process is consistent with basic rounding practices, making it clear why the correct answer reflects this logic.
