Question

Virginia is baking loaves of bread. For each loaf of bread, she uses 1/6 of a teaspoon of baking powder and 4 cups for flour. Virginia has a total of 4/7 of a teaspoon of baking powder and 15 cups of flour. She bakes as many whole loaves of bread as she can with the baking powder she has. What fraction of the flour did Virginia use?

Answer 1

She is baking loaves of bread . For each loaf of bread she uses 1/6 of a teaspoon of baking powder and 4 cups of flour.

`1\text{ loaf of bread = }(1)/(6)\text{teaspoon of powder + 4 cups of flour}`

What she possess to make bread is 4/7 teaspoon of powder and 15 cups of flour. Therefore the fraction of flour she can use with 4/7 teaspoon of baking powder can be computed below.

`\begin{gathered} (1)/(6)teaspoon=4\text{ cups of flour} \\ (4)/(7)\text{teaspoon}=\text{?} \\ \text{cross multiply} \\ (4)/(7)*4=(16)/(7)*6=(96)/(7)=13(6)/(7)\text{ cups of flour} \end{gathered}`

She uses 96/7 fraction of flour.
