Answer 1

Answer:5/12

Step-by-step explanation:2/3-1/4=5/12

Answer 2

For this case we must raise a rule three:

1 recipe ----------------------->
`\frac {2} {3}` butter

`\frac {1} {4}`recipe -------> x

Where the variable "x" represents the amount of butter that requires a quarter of the cookie recipe.

`x = \frac {\frac {1} {4} * \frac {2} {3}} {1}\\x = \frac {2} {12} = \frac {1} {6}`

So, Anna requires
`\frac {1} {6}` cup of butter

ANswer:

`\frac {1} {6}`
