Answer
4C, 2.5C, 5/3C, 4/3C, C, 3/4C, 3/5C, 2/5C, 1/4C
Work Step by Step
$C+C+C+C=4C$
$C+C+\frac{C}{2}=2.5C$
$C+\Big(\frac{1}{\frac{1}{2C}+\frac{1}{C}}\Big)^{-1}=\frac{5}{3}C$
$C+\frac{C}{3}=\frac{4}{3}C$
$\frac{C}{2}+\frac{C}{2}=C$
$\Big(\frac{1}{\frac{1}{3C}+\frac{1}{C}}\Big)^{-1}=\frac{3}{4}C$
$\Big(\frac{1}{\frac{1}{C}+\frac{C}{2}+C}\Big)^{-1}=\frac{3}{5}C$
$\Big(\frac{1}{\frac{1}{C}+\frac{1}{C}+\frac{1}{2C}}\Big)^{-1}=\frac{2}{5}C$
$\frac{C}{4}$
