If 100 treats will feed 15 dogs (each dog is given the same number of treats), how many dogs can be fed with 40 treats?
Lisa [10]

Answer: 6 dogs

Step-by-step explanation:

If 100 treats will feed 15 dogs, then that means that the number of treats that each dog requires is:

= 100/15

= 6.67 treats

If 6.67 treats will feed one dog then the number of dogs that will be fed by 40 is:

= 40 / 6.67

= 6 dogs
