(3|16+а)-38;а=5|12
(b+56)-34,b=1112
(415+58)-c,c=35
(15+d)-920,d=1316
(3/16 + а) - 3/8 = 3/16 + а - 6/16 = а - 3/16; а = 5/12
5/12 - 3/16 = 20/48 - 9/48 = 11/48
(b + 5/6) - 3/4 = b + 10/12 - 9/12 = b + 1/12; b = 11/12
11/12 + 1/12 = 12/12 = 1
(4/15 + 5/8) - с = 32/120 + 75/120 - с = 107/120 - с; с = 3/5
107/120 - 3/5 = 107/120 - 72/120 = 35/120 = 7/24
(1/5 + d) - 9/20 = 4/20 + d - 9/20 = d - 5/20 = d - 1/4; d = 13/16
13/16 - 1/4 = 13/16 - 4/16 = 9/16
