Rounding 389,422 when 8 is underlined

The underlined number is the number being rounded to. So you go to the number to the right of 8, if it's 1-4 your answer Stays the same except everything after the underlined number is 0, if it's 5-9 you add one to the underlined number and everything after is a 0. So your answer is 390,000. :) I hope this helps.
