In a zoo with animals, the ratio of mammals to reptiles to birds is
. How many birds does the zoo have?
Let be the number of mammals,
be the number of reptiles, and
be the number of birds.
Since the zoo has animals,
Because we want the number of birds, we need to find the value of .

On a desk, there are papers for every
paper clips and
papers for every
greeting card. What is the ratio of paper clips to total items on the desk?
Begin by making your life easier: presume that there are papers on the desk. Immediately, we know that there are
paper clips. Now, if there are
papers, you know that there also must be
greeting cards. Technically you figure this out by using the ratio:
By cross-multiplying you get:
Solving for , you clearly get
.
(Many students will likely see this fact without doing the algebra, however. The numbers are rather simple.)
Now, this means that our desk has on it:
papers
paper clips
greeting cards
Therefore, you have total items. Based on this, your ratio of paper clips to total items is:
, which is the same as
.

In a garden, there are pansies,
lilies,
roses, and
petunias. What is the ratio of petunias to the total number of flowers in the garden?
To begin, you need to do a simple addition to find the total number of flowers in the garden:
Now, the ratio of petunias to the total number of flowers in the garden can be represented by a simple division of the number of petunias by . This is:
Next, reduce the fraction by dividing out the common from the numerator and the denominator:
This is the same as .

In a classroom of students, each student takes a language class (and only one—nobody studies two languages).
take Latin,
take Greek,
take Anglo-Saxon, and the rest take Old Norse. What is the ratio of students taking Old Norse to students taking Greek?
To begin, you need to calculate how many students are taking Old Norse. This is:
Now, the ratio of students taking Old Norse to students taking Greek is the same thing as the fraction of students taking Old Norse to students taking Greek, or:
Next, just reduce this fraction to its lowest terms by dividing the numerator and denominator by their common factor of :
This is the same as .
