Answer:
21 articles of clothing are clean.
Step-by-step explanation:
If 2/5 clothes, or 40% of them, are dirty, then 3/5, or 60% of them are clean.
Multiply 35 by 0.60, and you get your answer.
35 x 0.60 = 21.
We can check this answer by multiplying 0.40 by 35 to get the amount of dirty clothes and adding that amount to 21, which should equal 35.
35 x 0.40 = 14
14 + 21 = 35
