To find out how many bags of clothes Stacy collected, we first need to determine how many bags Maura collected.
Maura collected \( 2 \frac{1}{5} \) bags of clothes. We can convert this mixed number into an improper fraction:
\[ 2 \frac{1}{5} = 2 + \frac{1}{5} = \frac{10}{5} + \frac{1}{5} = \frac{11}{5} \]
Now that we know Maura collected \( \frac{11}{5} \) bags of clothes, we can calculate how many bags Stacy collected. We know that Stacy collected \( \frac{1}{2} \) as many clothes as Maura did.
To calculate how many bags Stacy collected, we multiply Maura's amount by \( \frac{1}{2} \):
\[ \text{Stacy's bags} = \frac{1}{2} \times \frac{11}{5} = \frac{11}{10} \]
Now, we can express \( \frac{11}{10} \) as a mixed number:
\[ \frac{11}{10} = 1 \frac{1}{10} \]
Therefore, Stacy collected \( 1 \frac{1}{10} \) bags of clothes.
In summary, Stacy collected \(\boxed{1 \frac{1}{10}}\) bags of clothes.
