12 because 12 cubed is 1728
change both the fractions to improper fractions. the area will be 147/4 , and the width will be 9/2 . with both of these you may now divide, (147/4) / (9/2)
remember to use the KCF when dividing fractions.
147 * 2 = 294
4 * 9 = 36
your new fraction will be 294/36 .... which it is also 8 1/6
Y^2 -11y = 0
