Rica cleans 1/3 of the yard. Anna cleans 1/4 of the remaining. What fraction of the yard is left uncleaned?
Let's go step by step to solve this problem.
Rica cleans 1/3 of the yard, so the fraction of the yard that is left uncleaned after Rica is 1 - 1/3 = 2/3.
Anna cleans 1/4 of the remaining uncleaned yard, which is 2/3. So the fraction of the yard that is left uncleaned after Anna is 1 - (1/4)*(2/3) = 1 - 2/12 = 1 - 1/6 = 5/6.
Therefore, the fraction of the yard that is left uncleaned is 5/6.
