Answer:

Compare the first two numbers. Which is greater, 9,050 or 9,005?
9,050 = 9,000 + 50
9,005 = 9,000 + 5
50 > 5
So, 9,050 > 9,005.

Write the numbers from greatest to least.
9,050 9,005 9,500
Write the numbers in expanded form.
9,050 = 9,000 + 50
9,005 = 9,000 + 5
9,500 = 9,000 + 500
500 > 50 > 5
So, 9,500 > 9,050 > 9,005.
