Question

Kendra's backpack weighs 3 1⁄2 pounds. If she removes a book that weighs 13 ounces, how much does the backpack now weigh?

Answer 1

Answer:

2 lbs. 11 oz. Bc 3 1/2 = 3 pounds 8oz. 1pound = 16 Oz you would subtract 13 Oz from 3 pounds 8 ounces.

Weight of backpack:

3 1⁄2 pounds = (3 * 16) + (1⁄2 * 16) = 56 ounces

Weight of backpack with book removed:

56 - 13 = 43 ounces
