turn this to greatest to least: 8.4, 9.4, 14.2, 5.6, 8.3, 9.0, 10.2.

14.2, 10.2, 9.4, 9.0, 8.4, 8.3, 5.6.

To arrange the given numbers in descending order from greatest to least, follow these steps:

1. List the numbers: 8.4, 9.4, 14.2, 5.6, 8.3, 9.0, 10.2.

2. Identify the greatest number among them. In this case, it is 14.2.

3. Write down 14.2 as the first number.

4. Move on to the next greatest number: 10.2.

5. Write down 10.2 as the second number.

6. Continue this process with the remaining numbers: 9.4, 9.0, 8.4, 8.3, 5.6.

7. Write down the numbers in descending order: 14.2, 10.2, 9.4, 9.0, 8.4, 8.3, 5.6.

So, the numbers in greatest to least order are: 14.2, 10.2, 9.4, 9.0, 8.4, 8.3, 5.6.
