Answer:
cups of butter should be use to keep the same ratio.
Step-by-step explanation:
Given:
A recipe for pie dough calls for a ratio of butter to flour of 1/4 :5/6.
If you plan to use 5 cups of flour.
Now, to find the butter should be used to keep the same ratio.
So, to get the quantity of butter by using unitary method:
If, cup of flour use then butter should be =
.
So, 1 cup of flour use then butter should be = =
.
Thus, for 5 cups of flour butter should be = =
.
Therefore, cups of butter should be use to keep the same ratio.
