1/3-3/2+5/6 = 2/6-9/6+5/6 = -2/6
4/9+5/3.3/7+3/4 = 4/9+5/7+3/4 = 112/252+180/252+189/252 = 481/252
10/5+4/3.3/2+6/5-3/7 = 10/5+4/2+6/5-3/7 = 140/70+140/70+84/70-30/70 = 167/35
4/9+5/3.3/7+3/4 = 4/9+5/7+3/4 = 112/252+180/252+189/252 = 481/252
10/5+4/3.3/2+6/5-3/7 = 10/5+4/2+6/5-3/7 = 140/70+140/70+84/70-30/70 = 167/35
