12.5 pounds
13.5 pounds

Answer 1

the answer is 0.5 pounds

Answer 2

Answer:

Option B - 0.5 pounds

Step-by-step explanation:

Given : Irina measured the weight of her dog as 13 pounds

To find : What is the greatest possible error

Solution :

The greatest possible error in a measurement is half of the measuring unit.

We have the weight 13 pounds

13 pounds was measured to the nearest 1 pound, so the measuring unit is 1 pound.  

The GPE is half of the measuring unit.

$\frac{1}{2}=0.5$

The greatest possible error is 0.5 times 1 = 0.5 pounds.

Therefore, Option B is correct.
