Anna volunteers at a pet shelter. They have cats and dogs. There are 36 pets in total at the shelter, and the ratio of dogs to cats is 4:5. How many cats are at the shelter?

Ответ: 20 cats

Пошаговое объяснение:

Let dogs' number  is 4x => cats' number is 5x

Total: 4x+5x=36

9x=36

x=4

cats' number is 5x=5*4=20

The ratio of cats to dogs is 5:4, meaning for every 5 cats, there are 4 dogs. If there are 36 pets in total, we can set up an equation:(Number of cats) = (Number of dogs) * (5 / 4) = 36 * (5 / 4) = 45 cats
