Question

If one dog eats 5 pounds of food each week, how many dogs will 65 pounds of food feed for a week

Answer 1

It will feed 13 dogs.

Explanation:

1 dog = 5 lbs

Set up an equation:

Variable x = number of dogs

1/5 = x/65

Cross multiply:

1 × 65 = 5 × x

65 = 5x

Divide both sides by 5:

13

Check your work:

13 dogs × 5 lbs = 65 lbs

65 = 65

Correct!
