The local animal shelter has 120 dogs and cats. The ratio of dogs to cats is 3 to 7. How many dogs are in the shelter?

There are 36 dogs in the shelter.

Step-by-step explanation:

(Draw a model)

(3 boxes for dogs and 7 boxes for cats)

10 units = 120

1 unit = 120:10

= 12

3 units = 12*3

= 36

(I hope you understand the question. A gentle reminder, always draw the model according to the ratio. From there you will understand.)

There is 36 dogs and 84 cats
