Use rule of three to find the corresponding percentages:

Find the totals of each row and each column:

a. Percentage of copies of book A sold that are paperbacks

$x=\frac{442*100}{709}=62.34$

b. The percentage of copies of book B sold that are paperbacks:

$x=\frac{701*100}{888}=78.94$

c. the percentage of copies of book A sold that are e-books:

$x=\frac{267*100}{709}=37.66$

d. the percentage of copies of book B sold that are e-books:

$x=\frac{187*100}{888}=21.06$

e. the percentage of paperbacks sold that are copies of book A:

$x=\frac{442*100}{1143}=38.68$
