The ratio of dogs to cats at an animal shelter is 3 to 2. How many dogs are at the shelter if there is a total of 30 animals?
Since the ratio is 3 dogs to 2 cats, its a total of 5 animals
Therefore to find the number of dogs if a total of 30 animals are present you take
(3/5) x 30
To find the number of dogs at the animal shelter, we need to use the given ratio of dogs to cats, which is 3 to 2, and the total number of animals, which is 30.
First, we need to calculate the sum of the parts in the ratio, which is 3 + 2 = 5.
Next, we divide the total number of animals by the sum of the parts of the ratio: 30 ÷ 5 = 6.
Now, we can determine the number of dogs by multiplying the result by the ratio part for dogs: 6 × 3 = 18.
Therefore, there are 18 dogs at the animal shelter.
3x = # dogs
2x = # cats
3x+2x = 30
