Question

ABC is a three digit number where each number represents a different digit. If A < C what is the greatest possible number?

Answer 1

879

Explanation:

Because C is greater than A, C has to be the largest possible number so that A can be as large as possible. because C is the largest possible number, which is 9, the next largest number is 8, which in this case is A. The next biggest number is 7 which is B.

To sum it all up, the number is 879.
