计算:(+1.25)+(-1/2)+(-3/4)+(+1又3/4)-4又7/9+3又1/6-2又2/9-6又1/6计算:(+1.25)+(-1/2)+(-3/4)+(+1又3/4)-4又7/9+3又1

计算:(+1.25)+(-1/2)+(-3/4)+(+1又3/4)-4又7/9+3又1/6-2又2/9-6又1/6
计算:(+1.25)+(-1/2)+(-3/4)+(+1又3/4)
-4又7/9+3又1/6-2又2/9-6又1/6

计算:(+1.25)+(-1/2)+(-3/4)+(+1又3/4)-4又7/9+3又1/6-2又2/9-6又1/6
(+1.25)+(-1/2)+(-3/4)+(+1又3/4)
=(1又3/4-3/4)+(1.25-0.5)
=1+0.75
=1.75
-4又7/9+3又1/6-2又2/9-6又1/6
=-(4又7/9+2又2/9)+(3又1/6-6又1/6)
=-7-3
=-10
