Step 1: Make a table with the category names and counts. Step 2: Add a second column called “relative frequency”. I shortened it to rel. freq. here for space. Step 3: Figure out your first relative frequency by dividing the count by the total. For the category of dogs we have 16 out of 56, so 16/56=0.29. As a percent, the equation would be: (x) + (100-x) = 100, where the 100 designates the total percent in nature. If you set the equation as a decimal, this means the abundance would be equal to 1. The equation would then become: x + (1 – x) = 1. Note that this equation is limited to two isotopes.

The frequency of the Vanilla flavour is 30. The relative frequency of Vanilla flavour is calculated by dividing its frequency by the total number of responses.
