If 1/6 cup of icing covers 2/3 of a cake,
i.e 2/3 of cake is cover by = 1/6 cup of icing
then for 1 cake,
Divide 1/6 by 2/3
[tex]\begin{gathered} \frac{1}{6}\div\frac{2}{3} \\ \frac{1}{6}\div\frac{2}{3}=\frac{1}{6}\times\frac{3}{2} \\ \frac{1}{6}\div\frac{2}{3}=\frac{1}{2}\times\frac{1}{2} \\ \frac{1}{6}\div\frac{2}{3}=\frac{1}{4} \end{gathered}[/tex]Thus, 1 cake is cover by 1/4 cup of icing
