To solve this problem, we need to determine how many rolls Rosa can make with the dough she has, given the following information:

- Rosa has \( 3 \frac{3}{4} \) pounds of dough.
- Each roll uses \( \frac{1}{8} \) of a pound.

### Step-by-Step Solution:

1. **Convert the mixed number to an improper fraction:**
   - \( 3 \frac{3}{4} \) = \( \frac{15}{4} \).

2. **Divide the total amount of dough by the amount needed for one roll:**
   - This means dividing \( \frac{15}{4} \) by \( \frac{1}{8} \).
   - Division of fractions is the same as multiplying by the reciprocal, so:
     \[
     \frac{15}{4} \div \frac{1}{8} = \frac{15}{4} \times \frac{8}{1} = \frac{15 \times 8}{4 \times 1} = \frac{120}{4} = 30.
     \]

### Answer:
Rosa can make **30 rolls** with the dough she has.

Here are 5 related questions to expand on this topic:
1. How would the solution change if each roll required \( \frac{1}{4} \) of a pound of dough?
2. What if Rosa only had \( 2 \frac{1}{2} \) pounds of dough instead of \( 3 \frac{3}{4} \)?
3. How do you convert between mixed numbers and improper fractions?
4. Can you express the number of rolls as a decimal if she used \( \frac{1}{6} \) of a pound per roll?
5. How would you solve this if Rosa had \( 7 \frac{1}{2} \) pounds of dough?

**Tip:** When dividing fractions, always remember to multiply by the reciprocal of the second fraction for a quicker calculation.

Rosa has 3 3/4 pounds of dough. She uses 1/8 of a pound for one roll. How many rolls could be made from Rosa's dough?
