A word processor uses a sheet of paper that $9\text{ inches}$ wide by $12\text{ inches}$ long.

It leaves a $1\text{ inch}$ margin on each side and a $1.5\text{ inches}$ on the top and bottom.

Concept used:

  $\text{Fraction=}\frac{\text{area of page for text}}{\text{area of entire page}}$ .

Calculation:

Here the fraction will be:

  $\begin{array}{l}\text{Fraction=}\frac{\text{area of page for text}}{\text{area of entire page}}.\\ \Rightarrow \frac{\left(9-1-1\right)\left(12-1.5-1.5\right)}{9\times 12}.\\ \Rightarrow \frac{7}{12}.\end{array}$

Hence, the fraction of the page is used for the text is $\frac{7}{12}$ .
