Question

When Meredith cleaned her room she found that the ratio of clean clothes to dirty clothes was 2 to 5. If 35 articles of clothing were discovered, how many were clean?

Answer 1

21 articles of clothing are clean.

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
