Answer:
Explanation:
To write the ratio of the number of dogs to the total number of cats and dogs at the animal shelter, you first need to determine the number of dogs in the shelter.
Given that the ratio of cats to dogs is 4:5, you can break down the total number of animals into 9 equal parts (4 parts for cats and 5 parts for dogs).
Total parts = 4 (cats) + 5 (dogs) = 9 parts
Now, to find how many parts represent the number of dogs, you can use the proportion:
Number of dogs parts = (Number of dogs ratio) / (Total parts ratio)
Number of dogs parts = 5 / 9
Now, you can express the ratio of the number of dogs to the total number of cats and dogs:
Number of dogs to total number of animals = Number of dogs parts : Total parts
Number of dogs to total number of animals = 5 : 9
So, the ratio of the number of dogs to the total number of cats and dogs at the animal shelter is 5:9.
