Convert Hexadecimal $8D(16)$ to binary in signed magnitude

I’m supposed to covert hexadecimal value, $8D(16)$ into $8$-bit binary if signed magnitude representation is used.

$8D(16)$ $to$ $1000$ $1101(2)$

For signed magnitude, the left most bit is used to signify whether the value is a $+$ or $-$ value. In this case, how do I represent the value 8 into signed magnitude binary? Isn’t $1000$ equals to $-0$. I don’t see any possible way to write $8D$ in binary
