There is no meaningful question in "three over five y plus one over nine". There cannot, therefore, be an answer.
five over nine
0.95 or 19/20
Five over eight. 5/8
one and seven over twenty 1 7/20
1 7/12 (one and seven-twelfths)
you add five over 8 plus 4
eleven and twenty three over twenty four.
one and five eights
