Just want you check if my answer is right...i'm not good in math.
Ana paid 1/4 of her money for a pair of shoes and 1/5 of it for a shoulder bag. She later spent 3/8 less the remainder of her money for a dress. What part of her money did she pay for the dress?
Answer: 3/8 of 1/4 - 1/5
= 3/8 of 11/20 = 33/160
