The fractions are as follows: "Ri/Rt + Rr/Rm + Lt/Rp + Lm/Li + Lp/Lr." The numbers assigned to each print are based on whether or not they are whorls. A whorl in the first fraction is given a 16, the second an 8, the third a 4, the fourth a 2, and 0 to the last fraction. Arches and loops are assigned values of 0. Lastly, the numbers in
