Final answer:
After Margot donated 16.7% of her clothing, she chose to keep 83.3% of it. This is calculated by subtracting the donated percentage from the total 100%.
Step-by-step explanation:
If Margot chose to donate 16.7% of her clothing, we can calculate the percentage of clothing she chose to keep by subtracting this donated percentage from 100%. Since we start with 100% representing all of Margot's clothing, the remaining percentage after the donation represents the kept clothing.
To determine what percentage Margot kept, we use the following simple subtraction:
100% - 16.7% = 83.3%
So, Margot chose to keep 83.3% percent of her clothing after cleaning out her closet.
