Given the resistances of 1Ω, 2Ω, 3Ω, how will we combine them to get an equivalent resistance of (11/3):

 1 1Ω, 2Ω in parallel and the combination in series with 3Ω 2 3Ω, 2Ω in parallel and the combination in series with 1Ω 3 1Ω, 2Ω and 3Ω in parallel 4 1Ω, 2Ω in series and the combination in parallel with 3Ω
