Answer:
239,000
Step-by-step explanation:
Look at the digit to the right of the place you're rounding to. In this case, we are rounding to the thousands, so we look at the digit in the hundreds place. It's 8, which is above 5 (5 and above you round up. 4 and below, you round down). Because the 8 is above 5, we go back to the thousands place and bump the number (8) up one (to 9).
