One-fifth, two-fifths, three-fifths is 20%+20%+20% = 60% of the whole. 1,2,3,4,5...6 sixths is one. One, two, three, four, five-eights is 45 degrees times 5 (225 degrees). Oh, if my old math teacher could see me now.
I am precisely 160% sure (that's sixteen-tenths or 8/5 or one whole and eight-fifths) that they would be proud. I do not fear fractions anymore, and I'll shout that fact out loud. As this tale comes to an end, I'll count just one last thing: two, four, six-twelfths is just the same as half a solid ring.
