Question

The line plot shows the birth weights, in pounds, of a litter of 8 puppies.What is the difference in weight between the heaviest and lightest puppy?

Answer 1

ANSWER:

1/2 lb

STEP-BY-STEP EXPLANATION:

We can look at the 8 puppies, where the heaviest has a mass of 6/8 pounds and the lightest has a mass of 2/8 pounds.

We calculate the difference between these two weights, like this:

$d=\frac{6}{8}-\frac{2}{8}=\frac{6-2}{8}=\frac{4}{8}=\frac{1}{2}\text{ lb}$

What you mean between the weights is 1/2 of a pound
