Find the space between margins. Imagine the situation:
To find the space between margins, substract the distance of each margin to the width of the sheet of paper, to make this easier convert the mixed numbers to fractions or integers
[tex]\begin{gathered} 8\frac{1}{2}=\frac{17}{2} \\ 1\frac{1}{8}=\frac{9}{8} \end{gathered}[/tex][tex]d=\frac{17}{2}-\frac{9}{8}-\frac{9}{8}=\frac{17}{2}-\frac{9}{4}=\frac{50}{8}=\frac{25}{4}=6\frac{1}{4}[/tex]
