To convert the binary number $(10110.101)_{2}$ to a decimal number, we expand each digit by multiplying it with the corresponding power of 2 based on its position relative to the binary point. The conversion is calculated as follows: $$ \begin{aligned} (10110.101)_{2} &= 1 \times 2^{4} + 0 \times 2^{3} + 1 \times 2^{2} + 1 \times 2^{1} + 0 \times 2^{0} + 1 \times 2^{-1} + 0 \times 2^{-2} + 1 \times 2^{-3} \\ &= 16 + 0 + 4 + 2 + 0 + 0.5 + 0 + 0.125 \\ &= 22 + 0.625 \\ &= (22.625)_{10} \end{aligned} $$ Thus, the decimal equivalent is $(22.625)_{10}$.
