and help for part D

A) To write a ten-digit number using the given information, we can assign the digits to their respective places:

- Digit 4 is in billions place
- Digit 7 is in hundred millions place
- Digit 3 is in ten millions place
- Digit 5 is in millions, thousands, and ones place
- Digit 8 is in hundred thousand place
- Digit 2 is in ten thousand place
- Digit 9 is in hundreds place
- Digit 1 is in tens place

Using this information, we can construct the ten-digit number: 4,753,582,919.

B) To write the number in words, we can break it down into its individual digits and place values.

The number can be written as "Four billion, seven hundred fifty-three million, five hundred eighty-two thousand, nine hundred nineteen."

C) To round off the number to the nearest tens, hundreds, thousands, ten thousands, hundred thousands, millions, ten millions, and billions, we can follow the rounding rules:

- To the nearest tens: The tens digit remains the same, and all digits after the tens place are changed to zeros. In this case, the number becomes 4,753,582,920.
- To the nearest hundreds: The hundreds digit remains the same, and all digits after the hundreds place are changed to zeros. In this case, the number becomes 4,753,582,900.
- To the nearest thousands: The thousands digit remains the same, and all digits after the thousands place are changed to zeros. In this case, the number becomes 4,753,583,000.
- To the nearest ten thousands: The ten thousands digit remains the same, and all digits after the ten thousands place are changed to zeros. In this case, the number becomes 4,753,580,000.
- To the nearest hundred thousands: The hundred thousands digit remains the same, and all digits after the hundred thousands place are changed to zeros. In this case, the number becomes 4,753,600,000.
- To the nearest millions: The millions digit remains the same, and all digits after the millions place are changed to zeros. In this case, the number becomes 4,754,000,000.
- To the nearest ten millions: The ten millions digit remains the same, and all digits after the ten millions place are changed to zeros. In this case, the number becomes 4,750,000,000.
- To the nearest billions: The billions digit remains the same, and all digits after the billions place are changed to zeros. In this case, the number remains unchanged as 4,753,582,919.

D) The eight rounded numbers obtained in descending order are:
- 4,753,600,000
- 4,754,000,000
- 4,753,583,000
- 4,753,582,920
- 4,753,582,900
- 4,753,582,919 (original number)
- 4,753,580,000
- 4,750,000,000
