Question

cho used 2 1/3 cups of flour to bake a cake. she used 3 1/4 cups of flour to bake a loaf of bread. how much more flour did cho use to bake the loaf of bread than to bake the cake?

Answer 1

3 1/4 - 2 1/3 =
13/4 - 7/3 =
39/12 - 28/12 =
11/12

Answer 2

Hence, she used 11/12 cups of more flour to bake the loaf of bread than to bake the cake.

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:

`2(1)/(3)=(2* 3+1)/(3)\\\\i.e.\\\\2(1)/(3)=(7)/(3)\ cups`

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:

`3(1)/(4)=(3* 4+1)/(4)\\\\i.e.\\\\3(1)/(4)=(13)/(4)\ cups`

Hence, the extra quantity of flour that she use to bake the loaf of bread than to bake the cake is:

`=(13)/(4)-(7)/(3)\\\\\\=(13* 3-7* 4)/(4* 3)\\\\\\=(39-28)/(12)\\\\\\=(11)/(12)\ cups`
