Answer:
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.)
