Determine the greatest and the smallest two different digits numbers that can be formed using the digits 8, 5, and 7.
To find the greatest number, use the greatest digit (8) in the
tens place. Use the next greatest digit (7) in the units place.
So, the greatest two-digit number is 87.
To find the smallest number, use the smallest digit (5) in the
tens place. Use the next smallest digit (7) in the units place.
So, the smallest two-digit number is 57.
