Answer 1

((39/10-4/5)*2/3 / (3*3/2-5/2):5*2/3+ 19/20*1/3*1/6 / 3/20*5/9)*5/2-10/30
(31/10*1/3 / (9/2-5/2):5*2/3+ 19/90*1/3*1/6 / 1/4*1/3)*5/2-10/3
(31/5*1/3 / 2:5*2/3+19/901/6 / 1/4)*5/2-10/3
(31/15 / 2/5*2/3+19/540/1/4)*5/2-10/3
(31/15/4/15+19/135)*5/2-10/3
(31/4+19/135)*5/2-10/3
4261/540*5/2-10/3
4261/108*1/2-10/3
4261/216-10/3
3541/216=16 85/216,≈16,39352
