To arrange these numbers from least to greatest, you can compare them and order them based on their values. Here's how you can do it:

1. Start by comparing the whole numbers first: -2, 0, 2.
- The number -2 is the least.
- The number 0 comes next.
- Finally, the number 2 is the greatest.

2. Next, compare the decimal numbers: 0.02, 0.2.
- The number 0.02 is smaller than 0.2, so it comes before it.

Putting it all together, the numbers arranged from least to greatest are: -2, 0, 0.02, 0.2, 2.
