rational numbers

Alex17521 [72]

Answer: A

Step-by-step explanation:

First, we know that each set has 20 kL, 20 L, and 20 ml. To know if they are in the order from greatest to least, we should make sure all three have the same units. Once we do, we can put them in order.

20 kL=20000 L

20 mL=0.02 L

20 L=20L

Now that we have made sure the units are all the same, we know that 20 kL is the greatest and 20 mL is the smallest. The final order is 20 kL, 20 L, 20 mL.
