Question

Zoron had a sheet of paper 8 1/2 in. wide. He left a margin 1 1/8 in. wide on both sides of the paper. How wide was the space between the margins?

Answer 1

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

$\begin{gathered} 8\frac{1}{2}=\frac{17}{2} \\ 1\frac{1}{8}=\frac{9}{8} \end{gathered}$$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}$
