We are going to make the largest and smallest 3-digit numbers from three given digits.

Let's pretend we can only use the digits 5, 4 and 8.

**To make the largest number:**

Start with the largest digit in the Hundreds column.

This is 8.

Then comes the next largest digit in the Tens column.

This is 5.

Lastly comes the smallest of the three digits in the Ones column.

This is 4.

The largest number is 854

**To make the smallest number:**

Start with the smallest digit in the Hundreds column.

This is 4.

Then comes the next largest digit in the Tens column.

This is 5.

Lastly comes the largest of the three digits in the Ones column.

This is 8.

The smallest number is 458.

**Example**

Use each of the digits:

686

to form the smallest and largest 3-digit numbers that you can make.

**Answer**

6 is the smallest digit.

6 is the "middle" digit even though it is the same as the smallest here.

8 is the largest digit.

Smallest number is 668.

Largest number is 866.
