The binary code for $m$ is:
$1101101$
Work Step by Step
The essay states that the lowercase letter $m$ is assigned the number $109$.
To find the binary representation for this, use division.
The place values in base two are $..., 2^7, 2^6, 2^5, 2^4, 2^3, 2^2, 2^1, 1$
The place values that are less than or equal to $109$ are $2^6, 2^5, 2^4, 2^3, 2^2, 2^1$ and $1$.
Divide $109$ by $2^6$ or $64$:
$109 \div 64 = 1$ remainder $45$
Divide $45$ by $2^5$ or $32$
$45 \div 32 = 1$ remainder $13$
Divide $13$ by $2^4$ or $16$:
$13 \div 16 = 0$ remainder $13$
Divide $13$ by $2^3$ or $8$:
$13 \div 8 = 1$ remainder $5$
Divide $5$ by $2^2$ or $4$:
$5 \div 4=1$ remainder $1$
Divide $1$ by $2^1$ or $2$:
$1 \div 2 = 0$ remainder $1$
Divide $1$ by $1$:
$1 \div 1 = 1$
Thus,
$109 = (1 \times 2^6) + (1 \times 2^5) + (0 \times 2^4)+(1 \times 2^3)+(1\times 2^2) + (0 \times 2^1)+(1 \times 1)
\\109=1101101_{\text{two}}$
