Answer:
Hence, she used 11/12 cups of more flour to bake the loaf of bread than to bake the cake.
Step-by-step explanation:
It is given that:
Cho used 2 1/3 cups of flour to bake a cake.
i.e. in simple fraction the amount of flour she used to baker the cake is given by:
[tex]2\dfrac{1}{3}=\dfrac{2\times 3+1}{3}\\\\i.e.\\\\2\dfrac{1}{3}=\dfrac{7}{3}\ cups[/tex]
and she used 3 1/4 cups of flour to bake a loaf of bread
and in simple fraction the amount of cups of flour she used to bake a loaf of bread is:
[tex]3\dfrac{1}{4}=\dfrac{3\times 4+1}{4}\\\\i.e.\\\\3\dfrac{1}{4}=\dfrac{13}{4}\ cups[/tex]
Hence, the extra quantity of flour that she use to bake the loaf of bread than to bake the cake is:
[tex]=\dfrac{13}{4}-\dfrac{7}{3}\\\\\\=\dfrac{13\times 3-7\times 4}{4\times 3}\\\\\\=\dfrac{39-28}{12}\\\\\\=\dfrac{11}{12}\ cups[/tex]
