At a dog shelter, a 28-pound bag of dog food will feed 42 dogs. How many dogs would you expect to feed with a 14-pound bag of dog food? (Input only whole numbers.)

Respuesta :

 Form and solve an equation of ratios:

 14 lb          x
--------- = ------------
 28 lb       42 dogs

then (28 lbs)x = (14 lb)(42 dogs, and x = 21 dogs (can be fed with a 14-lb bag)
21 dogs will be able to be fed with 14lbs of dog food
