Problem Solving
Recipe A makes 5 dinner rolls using 1 c of flour. Recipe B makes 24 rolls using 7 1/2 c of flour. which recipe requires the most flour per roll
- To know which recipe requires the most flour per roll, let's convert fraction to decimal.
before that let's convert the recipe B from mixed fraction to decimal then, the total is the numerator and make 24 as the denominator.
How do we convert fraction to decimal?
- Divide the numerator by the denominator.
- [tex] \tt\frac{1}{2} = 0.5[/tex]
- Then, add the whole number. ( if it is mixed fraction)
- [tex] \tt 0.5 + 7 = 7.5[/tex]
Recipe B
- [tex]\tt 7.5\div 24 =0.31[/tex]
[tex]\rightarrow[/tex]Recipe B [tex] \tt =\frac{7.5}{24}=0.31[/tex]
Recipe A
- [tex] \tt 1\div 5=0.2[/tex]
[tex]\rightarrow[/tex]Recipe A [tex] \tt = \frac{1}{5}=0.2[/tex]
Recipe B is great than Recipe A
Therefore, Recipe B requires the most flour per roll.
