Explanation: For Column A: Look only at the size of the premium sales
column, without the regular sales: 9-10/10=-1/10. B : 15-16/16=-1/16.
Don’t worry about converting to percent. Just compare the
absolute values of the fractions. Although the value on the number line
of a negative sixteenth is further to the right (greater value on the
number line) than is a negative tenth, in this case the tenth (10%) is the
larger change.
