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

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

ascending - from smallest to greatest

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