The first week of January, there are

49 dogs and 28 cats in an animal shelter.
Throughout the month, the ratio of dogs
to cats remains the same. The last week
of January, there are 20 cats in the
shelter. How many dogs are there?

There are 35 dogs

The ratio of dogs to cats are 49:28

28/20=1.4
28/1.4=20 (double checking)

Since it’s equivalent ratios, we also do the same with the ratio of dogs

49/1.4=35

Therefore, there are 35 dogs.
