Answer:
8: thousands place, 5,000
9: millions place, 6 million
Explanation:
Place value is quite confusing at first, but it gets to be much easier. Basically, every time you add a place on a number, you are increasing its place value! Lets use number 9 for example. The one in this number is in the ones place. You know this because it is the last digit. The 4, is the tens place, since it is directly to the left of the ones place. You are increasing the place value to the left. The order of place value is:
Ones
Tens
Hundreds
Thousands
Ten thousands
Hundred thousands
Millions
Ten Millions
Hundred Millions
Billions
and so on. I hope this was helpful!
