Remember your numbers -

The higher the negative number the less value it has.

The higher the positive number to more value it has.

To put these numbers from least to greatest, follow these steps:

1. Start by arranging the numbers within each set separately.
Set 1: -13, 0, -7, 7, 1
Set 2: 25, -2.1, 1, -2.2, 0

2. Now, let's sort the numbers within Set 1:
-13, -7, 0, 1, 7

3. Next, we'll sort the numbers within Set 2:
-2.2, -2.1, 0, 1, 25

4. Finally, combine the two sets and sort them all together:
-13, -7, -2.2, -2.1, 0, 0, 1, 1, 7, 25

So, from least to greatest, the numbers are:
-13, -7, -2.2, -2.1, 0, 0, 1, 1, 7, 25
