dogs in 30 will be =
$\frac{3 \times 30}{5}$

And 12 cats in the shelter.



hope it helps you

Answer 2

The ratio of dogs and cats is 3:2
Let the dogs at shelter are 3x
Then cats must be 2x
Total no. of animals if only cats and dogs are present there = 2x +3x =30
=>5x=30
=> x= 6
No.of dogs = 3x=3×6 =18
