Answer 1

1) 475320 - four hundred seventy-five thousand three hundred twenty
(4 x 100,000) + (7 x 10,000) + (5 x 1,000) + (3 x 100) + (2 x 10)
 
2) 9847215 - nine million eight hundred forty-seven thousand two hundred fifteen
(9 x 1,000,000) + (8 x 100,000) + (4 x 10,000) + (7 x 1,000) + (2 x 100) + (1 x 10) + (5 x 1)

3) 97645310 - ninety-seven million six hundred forty-five thousand three hundred ten
(9 x 10,000,000) + (7 x 1,000,000) + (6 x 100,000) + (4 x 10,000) + (5 x 1,000) + (3 x 100) + (1 x 10)

4) 30458094 - thirty million four hundred fifty-eight thousand ninety-four
(3 x 10,000,000) + (4 x 100,000) + (5 x 10,000) + (8 x 1,000) + (9 x 10) + (4 x 1)

The smallest number is 475,320
The greatest number is 97,645,310

ascending - from smallest to greatest
descending - from greatest to smallest

I'll just do ascending order, the descending is the opposite of the ascending order.

475,320 ⇒ 9,847,215 ⇒ 30,458,094 ⇒ 97,645,310
