An animal shelter has 104 cats and dogs. The ratio of cats to dogs is 5:3. How many cats are at the shelter?
Aneli [31]

Answer:

65 cats

Step-by-step explanation:

cats: dogs: total

5:     3:        5+3=8

We need 8 to be 104

104/8 = 13

Multiply each by 13

cats: dogs: total

5*13:   3*13:  8*13

65        39     104

There are 65 cats and 39 dogs
