The local animal shelter has 120 dogs and cats. The ratio of dogs to cats is 3 to 7. How many dogs are in the shelter?

There are 36 dogs in the shelter.

Step-by-step explanation:

(Draw a model)

(3 boxes for dogs and 7 boxes for cats)

10 units = 120

1 unit = 120÷10

= 12

3 units = 12×3

= 36

(I hope you understand the question. A gentle reminder, always draw the model according to the ratio. From there you will understand.)

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
