To convert the binary number $101101101$ to decimal, we interpret each binary digit as a power of 2, starting from the right (the least significant bit).

The binary number $101101101$ can be expanded as follows:

$1 \times 2^8 + 0 \times 2^7 + 1 \times 2^6 + 1 \times 2^5 + 0 \times 2^4 + 1 \times 2^3 + 1 \times 2^2 + 0 \times 2^1 + 1 \times 2^0$

Calculating each term:

$1 \times 2^8 = 256$ $0 \times 2^7 = 0$ $1 \times 2^6 = 64$ $1 \times 2^5 = 32$ $0 \times 2^4 = 0$ $1 \times 2^3 = 8$ $1 \times 2^2 = 4$ $0 \times 2^1 = 0$ $1 \times 2^0 = 1$

Now, adding these values:

$256 + 0 + 64 + 32 + 0 + 8 + 4 + 0 + 1 = 365$

So, the decimal equivalent of the binary number $101101101$ is:

$\boxed{365}$
