#### Answer

56 ounces

#### Work Step by Step

Use a unit fraction with ounces (the unit for your answer) in the numerator, and pounds (the unit being changed) in the denominator. Because 1 lb = 16 ounces, the necessary unit fraction is
(16 ounces)/(1 lb)
Multiply 9 in times the unit fraction
7/2 lb* (16 ounces)/(1 lb)= 56 ounces
