Rosa has [tex]$3 \frac{3}{4}$[/tex] pounds of dough. She uses [tex]$\frac{1}{8}$[/tex] of a pound for one roll. How many rolls can be made from Rosa's dough?

A. [tex][tex]$3 \frac{1}{6}$[/tex][/tex]
B. 18
C. 30



Answer :

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.
