1)  3*1/5 = 3*1+5/5 = 8/5
1*2/3 = 1*2+3/3 = 2+3 /3 = 5/3 
5/3+2/5 = 5)5/3 + 3)2/5 = 5*5/5*3 + 3*2/3*5 = 25/15 +6/15 = 31/15
1*3/16 = 1*3+16/16= 19/16
8/5 / 31/15 * 19/16 = 
1.1) 8/5 / 31/15 = 8/5*15/31 = 120/155
1.2) 120/155*19/16 = 2280/2480(2 = 1140/1240(2 = 570/620(2= 485/310
                      raspuns : 8/58 / 31/15* 19/16 = 485/310
