B. 9 lb. 6 oz.
C. 12 lb. 20 oz.
D. 10 lb. 5 oz.

Respuesta :

b is the answer there is net weight we needed just subtract from each other
For this case, what we must do is add the corresponding units correctly.
 We then take the following measures:
 11 pounds 5 ounces
 1 pound 15 ounces
 The net weight, we obtain it by subtracting both quantities.
 We have the following conversion:
 1 pound = 16 ounces
 We have then:
 (11 pounds 5 ounces) - (1 pound 15 ounces)
 Rewriting we have:
 (11 pounds + (5/16) pounds) - (1 pound + 15/16 pounds)
 (11.3125 pounds) - (1.9375 pounds)
 9,375 pounds
 (9 pounds + 0.375 * 16 ounces)
 (9 pounds + 6 ounces)
 Answer:
 The net weight of the contents is:
 B. 9 lb. 6 oz.
