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,how much butter shoul

Komok [63]

Answer:

$\frac{3}{2}$ 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, $\frac{5}{6}$ cup of flour use then butter should be = $\frac{1}{4}$ .

So, 1 cup of flour use then butter should be = $\frac{1}{4} \div \frac{5}{6}$ = $\frac{6}{20}$ .

Thus, for 5 cups of flour butter should be = $\frac{6}{20} \times 5$ = $\frac{30}{20}=\frac{3}{2}$ .

Therefore, $\frac{3}{2}$ cups of butter should be use to keep the same ratio.
