(See explanation below for further details)

Explanation:

First, each ingredient is recalculated herein:

Butter

`(30)/(20)* (1)/(2)`

`(3)/(2) * (1)/(2)`

`(3)/(4)`

Sugar

`(30)/(20)* (4)/(3)`

`(3)/(2) * (4)/(3)`

`2`

Baking soda

`(30)/(20) * (1)/(4)`

`(3)/(2) * (1)/(4)`

`(3)/(8)`

Egg

`(30)/(20) * (2)/(2)`

`(3)/(2) * (2)/(2)`

`(3)/(2)`

Vanilla

`(30)/(20) * (1)/(2)`

`(3)/(2) * (1)/(2)`

`(3)/(4)`

Flour

`(30)/(20) * (3)/(2)`

`(3)/(2) * (3)/(2)`

`(9)/(4)`

The Sugar Cookies recipes is re-written as follows:

3/4 c. butter
