To determine how many rolls Rosa can make with her [tex]$3 \frac{3}{4}$[/tex] pounds of dough when each roll uses [tex]$\frac{1}{8}$[/tex] of a pound, let's follow the steps:
1. Convert the mixed fraction to an improper fraction or a decimal:
Rosa has [tex]\(3 \frac{3}{4}\)[/tex] pounds of dough. To convert this mixed number to a decimal:
[tex]\[
3 \frac{3}{4} = 3 + \frac{3}{4} = 3 + 0.75 = 3.75 \text{ pounds}
\][/tex]
2. Understand the amount of dough needed for one roll:
Each roll requires [tex]\(\frac{1}{8}\)[/tex] of a pound of dough. To convert this to a decimal:
[tex]\[
\frac{1}{8} = 0.125 \text{ pounds}
\][/tex]
3. Calculate the number of rolls that can be made:
To find out how many rolls can be made, divide the total amount of dough by the amount needed for one roll:
[tex]\[
\text{Number of rolls} = \frac{3.75 \text{ pounds}}{0.125 \text{ pounds/roll}}
\][/tex]
4. Perform the division:
[tex]\[
\frac{3.75}{0.125} = 30 \text{ rolls}
\][/tex]
So, Rosa can make 30 rolls with her [tex]$3 \frac{3}{4}$[/tex] pounds of dough.
