Put these numbers in order smallest to largest 0.6. 0.06. 0.43. 0.9

0.006, 0.43, 0.6, 0.9

To put these numbers in order from smallest to largest, you can follow these steps:

1. Compare the whole numbers of the given decimal numbers. In this case, there are none since all the decimal numbers have a whole part of zero.

2. Compare the decimal parts of the numbers starting with the first decimal place. In this case, the decimal parts are 6, 06, 43, and 9.

3. The smallest decimal part is 06, followed by 6, 9, and 43. Rearrange the decimal numbers in this order: 0.06, 0.6, 0.9, and 0.43.

So, the numbers in order from smallest to largest are: 0.06, 0.6, 0.9, and 0.43.
