Question

a backpack weighed 28 pounds. If you take out a textbook that weighs 6 pounds and 3 ounces, how much will the backpack weigh

Answer 1

21 pounds and 13 ounces is the correct answer 

Answer 2

Answer:

Step-by-step explanation:

Given : The weight of bag pack = 28 pounds

We know that 1 pound = 16 ounces

Then $28\text{ pounds}=28\times16\ \text{ounces}=448 \text{ounces}$

Also, the weight of textbook = 6 pounds and 3 ounces

Now,  $6\text{ pounds}=6\times16\ \text{ounces}=96 \text{ounces}$

Then, the weight of textbook = 96 ounces +3 ounces = 99 ounces

So, if we take out the textbook, then the weight of bag pack =$448-99=349\text{ounces}$

In pounds, the weight of bag pack will be 21 pounds and 13 ounces. [divide 349 by 16]
