Answer:
[tex]\frac{2}{27}[/tex]
Step-by-step explanation:
We have given that melissa used 4 cups of sugar to bake 54 cookies.
That means 1 cup of sugar will be used to bake [tex]\frac{54}{4}=\frac{27}{2}[/tex] by unitary method
We have to find the ratio of cups to the cookies
We are using 1 cup of sugar
And cookies will be [tex]\frac{27}{2}[/tex]
[tex]\text{equivalent ratio}=\frac{1}{\frac{27}{2}}=\frac{2}{27}[/tex]
