谢了,急求,急啊!一定要过程!急
1/8÷12.5%×(2/3+3/4) (6.7×60％+3.3×60％)÷1/4
6.25％×19/18-1/18×5/8 25×（1+40％）这样清楚点,悬赏什么的加是可以的啊急求
答
1/8÷12.5%×(2/3+3/4) (6.7×60％+3.3×60％)÷1/4
=(1/8×1000/125)×(2/3+3/4) =(60%×(6.7+3.3))÷1/4
=(1/8×8)×(8/12+9/12) =(60%×10)÷1/4
=1×17/12 =6÷1/4
=17/12 =6×4
=1又5/12 =24
6.25％×19/18-1/18×5/8 25×（1+40％）
=625/10000×19/18-1/18×5/8 =25+25×40%
=5/8×19/18-1/18×5/8 =25+10
=5/8×(19/18-1/18) =35
=5/8×1
=5/8
