In a certain neighbourhood the ratio of cats to dogs to squirrels to skunks is 5:4:7:1. If there are 119 of these animals in all, how many are dogs?

4/(5+4+7+1) *119 = ?

119 + 4

hi

The answer is 28.

To find out how many dogs there are in the neighborhood, we need to determine the ratio of dogs to the total number of animals.

First, let's calculate the total number of parts in the given ratio (5:4:7:1), which is the sum of the individual ratios: 5 + 4 + 7 + 1 = 17.

Next, we need to find the value of one part. Since the total number of animals in the neighborhood is 119, we divide this number by the total number of parts: 119 / 17 = 7.

Now that we know the value of one part, we can calculate the number of dogs by multiplying the value of one part by the ratio of dogs to the total number of parts. In this case, the ratio of dogs is 4, so the number of dogs is 7 * 4 = 28.

Therefore, there are 28 dogs in the neighborhood.
