1/50+1 цел37/100=1/50+137/100=(2+137)/100=139/100=1,39

-(711/100+1/2)=-((711+50)/100)=-761/100=-7,61

2/3-8/10=(20-24)/10=-0,4

-2/7*14/10=-28/70=-0,4

-24/100*(-3/160)=72/16000=0,0045

42/10:(-6/7)=-42*7/10*6=-294/60=-4,9

16/100:12/5=16*5/100*12=80/1200=8/120=2/30

16/5:64/100=1600/(5*64)=1600/320=5
