Answer:
600,000
Step-by-step explanation:
You look at the digit in the hundred thousands place (6). You look at the place value position to the right. If there is a 5 or greater, you round up. Four or less your number stays the same.
In this case there is a 4 in the ten thousands place. So, the number 6 will stay a six and everything else becomes a zero.
647,955 is closer to 600,000 than 700,000.
