To find out how many bags of oranges Pamela used on Tuesday, we need to calculate \( \frac{7}{8} \) of the number of bags she used on Monday.
On Monday, she used 10 bags of oranges. So, we calculate \( \frac{7}{8} \times 10 \):
\[ \frac{7}{8} \times 10 = \frac{7 \times 10}{8} = \frac{70}{8} \]
Next, we simplify \( \frac{70}{8} \):
\[ \frac{70}{8} = \frac{35}{4} \]
Now, we can express \( \frac{35}{4} \) as a mixed number. To do this, we divide 35 by 4:
- 35 divided by 4 gives 8, with a remainder of 3.
So, we can write \( \frac{35}{4} \) as:
\[ 8 \frac{3}{4} \]
Thus, the number of bags of oranges Pamela used on Tuesday is \( \frac{35}{4} \) or \( 8 \frac{3}{4} \).
In summary, Pamela used \( \frac{35}{4} \) bags of oranges on Tuesday.
