Lizzy: The sky currently has 4 times as many cirrus clouds as cumulus clouds, and 12 times as many cumulus clouds as cumulonimbus clouds. If the sky currently has 3 cumulonimbus clouds, how many cirrus clouds are in the sky at this moment?.
Me: Hmmm, let me think. I think this is the detailed solution:
The sky has 3 * 12 = 36 cumulus clouds. The sky has 4 * 36 = 144 cirrus clouds. Final answer: 144.
