The circle externally tangent to circles with the fractions a/b and c/d has the fraction (a+c) /(b/d). The amazing thing is that all fractions are in simplest form, every fraction will eventually appear, and the centers correspond to the fraction aka the center of the 2/3 circle is 2/3 of the way from the center of the 0/1 circle to the 1/1 circle
