 ( 3 -1 58 ) * ( 4 - 1 311 ) : (5 - 1 14) = 

Answer 1

( 1 - 14 + 38 ) : 34 - 12=(8-2+3)/8:3/4-1/2=9/8·4/3-1/2=3/2-1/2=1

( 1 78 + 7 10 ) : 38 - 25 = 1 (35+28)/40:3/8-2/5= 1 63/40:3/8-2/5=103/40·8/3-2/5=103/15-2/5=97/15=6 7/15

2 *1 5 12 + 4 * 18 + 1 19 * 1 14 = 2·17/12+1/2+10/9·5/4=17/6+1/2+25/18=2  5/6+1/2+ 1 7/18=3 31/18= 4 13/18

( 16 + 1 10 + 115 ) : ( 35 - 13 - 14) = (5+3+2)/30 : (36-20-15)/60=10/30·60=20

 ( 3 -1 58 ) * ( 4 - 1 311 ) : (5 - 1 14) = (2-5/8)·(3-3/11):(4-1/4)=1 3/8·2 8/11:3 3/4=11/8·30/11·4/15=1
