Answer 1

Step-by-step explanation:

8. = 1. Smallest = 2469

Greatest = 9642

2. Smallest = 3078

Greatest = 8703

9. = 1. Smallest = 23469

Greatest = 96432

2. Smallest = 5089

Greatest = 9805

10. = 1. Smallest = 56789

2. Greatest = 97378

11. = a). 2 thousands

12. = 1. a). 10001 = successor = 10000

= predecessor = 10002

b). 19999 = successor = 19998

= predecessor = 100000

c). 20000 = successor =19999

= predecessor = 20001
