Answer 2

To add the given measurements, you need to ensure that you're adding like units together. Here are the calculations:

1. 21 decimeters + 9 decimeters = 30 decimeters
2. 64 centimeters + 9 centimeters = 73 centimeters
3. 51 kilograms + 9 kilograms = 60 kilograms
4. 77 kilograms + 3 kilograms = 80 kilograms
5. 83 liters + 71 liters = 154 liters
6. 45 liters + 5 liters = 50 liters
7. 32 decimeters + 8 decimeters = 40 decimeters
8. 23 centimeters + 7 centimeters = 30 centimeters
9. 52 liters + 8 liters = 60 liters

So, those are the results of the additions.
