Jean still has \( 6 \frac{1}{3} \) pounds of apples, which is equivalent to \( \frac{19}{3} \) pounds.
Solución
To find out how many pounds of apples Jean still has after using some to make pies, we need to subtract the amount she used from the total amount she had.
1. **Convert the mixed numbers to improper fractions:**
- For \( 8 \frac{4}{9} \):
\[
8 \frac{4}{9} = \frac{8 \times 9 + 4}{9} = \frac{72 + 4}{9} = \frac{76}{9}
\]
- For \( 2 \frac{1}{9} \):
\[
2 \frac{1}{9} = \frac{2 \times 9 + 1}{9} = \frac{18 + 1}{9} = \frac{19}{9}
\]
2. **Subtract the two fractions:**
\[
\frac{76}{9} - \frac{19}{9} = \frac{76 - 19}{9} = \frac{57}{9}
\]
3. **Simplify the fraction if possible:**
\[
\frac{57}{9} = 6 \frac{3}{9} = 6 \frac{1}{3}
\]
Now, let's check the answer choices:
- a \( \quad \frac{105}{9} \) pounds
- b 6 pounds
- c \( \frac{61}{3} \) pounds
- d 6 apples
To convert \( 6 \frac{1}{3} \) to an improper fraction:
\[
6 \frac{1}{3} = \frac{6 \times 3 + 1}{3} = \frac{18 + 1}{3} = \frac{19}{3}
\]
Now, let's convert \( \frac{57}{9} \) to a fraction with a denominator of 3:
\[
\frac{57}{9} = \frac{57 \div 3}{9 \div 3} = \frac{19}{3}
\]
Thus, Jean still has \( 6 \frac{1}{3} \) lbs of apples, which is equivalent to \( \frac{19}{3} \) lbs.
The correct answer is:
c \( \frac{61}{3} \) pounds.

To find out how many pounds of apples Jean still has, you start by subtracting the amount used for pies from the initial amount. Convert the mixed numbers to improper fractions: \( 8 \frac{4}{9} = \frac{76}{9} \) and \( 2 \frac{1}{9} = \frac{19}{9} \). Now perform the subtraction: \( \frac{76}{9} - \frac{19}{9} = \frac{57}{9} \). After converting back to a mixed number, \( \frac{57}{9} = 6 \frac{3}{9} = 6 \frac{1}{3} \). So, the correct answer is c \( \frac{61}{3} \) pounds.
