To find the percentage of dirt in the mud pie, we need to determine the part of the mud pie that consists of dirt and divide it by the total number of parts in the mud pie.
The mud pie recipe calls for 2 parts of dirt out of a total of 5 parts (1 part green grass + 2 parts dirt + 1 part pebbles + 1 part water).
Therefore, the percentage of the mud pie that is dirt is:
(2 parts of dirt / 5 total parts) * 100 = 40%
Therefore, the correct answer is 40%.
