Formula for Phenotypic Ratio?

Divide each frequency by the smallest one, and note the answer in the margins of the table. For example, if there are 10 in category one and 30 in category two, 10 divided by 10 equals 1 and 30 divided by 10 equals 3. Write the phenotypic ratio using rounding when appropriate.
