计算:(-2/3)+(0.25)+(-1/6)-(+1/2)=?(3又3/5)+(+4又3/4)-(+1又2/5)+(-3又3/4)计算:(-2/3)+(0.25)+(-1/6)-(+1/2)=?(3

计算:(-2/3)+(0.25)+(-1/6)-(+1/2)=?(3又3/5)+(+4又3/4)-(+1又2/5)+(-3又3/4)
计算:(-2/3)+(0.25)+(-1/6)-(+1/2)=?(3又3/5)+(+4又3/4)-(+1又2/5)+(-3又3/4)

计算:(-2/3)+(0.25)+(-1/6)-(+1/2)=?(3又3/5)+(+4又3/4)-(+1又2/5)+(-3又3/4)
-8/12 + 3/12 - 2/12 - 6/12=13/12
[(3又3/5)-(+1又2/5)]+[(+4又3/4)+(-3又3/4)]=2又1/5+1=16/5(或3又1/5)
