Question

a package of paper weighs 2 1/9 oz. If Mike put 4 1/2 packages of paper on a scale, how much would they weigh?

Answer 1

This is solved by multiplying 2 1/9 by 4 1/2. The easiest way to do this is by making these improper fractions:

 

19/9 x 9/2

 

Multiply the numerators together (19 x 9) and the denominators together (9x2). This will tell you the total number of ounces: 171/18 = 9.5 ounces
