25/14 cup of butter are required to make 10 dozen cookies.
<u>Step-by-step explanation</u>:
Cup of butter required to make 4 dozen cookies = 5/7
<u>To find 1 dozen cookies</u> :
Rate = Cup of butter required / number of dozen
Let, the cup of butter for 1 dozen be'x'.
⇒ (5/7) / 4 = x/1
⇒ x = 5/28
<u>The cup of butter required for 10 dozen of cookies</u> :
⇒ 10 (cup of butter for 1 dozen cookies)
⇒ 10 5/28
⇒ 50/28
⇒ 25/14
Therefore, 25/14 cup of butter are required to make 10 dozen cookies.
