By arranging, 8Ω and 12Ω in a series connection and then the connection of the resultant in parallel with 16Ω.

When arranging the 8Ω and 12Ω in a series,

8 Ω + 12Ω= 20 Ω

Now, taking this 20Ω and arranging it in parallel combination with the 16Ω,

we get,

\frac{1}{r} = \frac{1}{20} + \frac{1}{16}

\frac{1}{r} = \frac{9}{80}

r = \frac{80}{9}

∴ r = 8.89 Ω
