Rosa has \( 3 \frac{3}{4} \) pounds of dough. She uses \( \frac{1}{8} \) of a pound for one roll. How many rolls could be made from Rosals dough? 18 30 \( 3 \frac{1}{6} \) 9

To determine how many rolls Rosa can make from her dough, we need to follow these steps: 1. **Convert the mixed number to an improper fraction**: Rosa has \( 3 \frac{3}{4} \) pounds of dough. We convert this to an improper fraction. \[ 3 \frac{3}{4} = \frac{3 \times 4 + 3}{4} = \frac{12 + 3}{4} = \frac{15}{4} \] 2. **Determine how much dough is used for one roll**: Rosa uses \( \frac{1}{8} \) of a pound for one roll. 3. **Calculate the number of rolls**: To find out how many rolls can be made, we divide the total amount of dough by the amount used for one roll: \[ \text{Number of rolls} = \frac{\text{Total dough}}{\text{Dough per roll}} = \frac{\frac{15}{4}}{\frac{1}{8}} \] Dividing by a fraction is the same as multiplying by its reciprocal: \[ \frac{15}{4} \div \frac{1}{8} = \frac{15}{4} \times \frac{8}{1} = \frac{15 \times 8}{4 \times 1} = \frac{120}{4} = 30 \] Thus, Rosa can make **30 rolls** from her dough. The answer is \( 30 \).
