一道简便计算-100乘1/8-0.125乘35.5+14.5乘(-12.5%)
一道简便计算
-100乘1/8-0.125乘35.5+14.5乘(-12.5%)

一道简便计算-100乘1/8-0.125乘35.5+14.5乘(-12.5%)
-100乘1/8-0.125乘35.5+14.5乘(-12.5%)
=1/8*(-100-35.5-14.5)
=1/8*(-150)
=-75/4.

-18.75

=-12.5-0.125(35.5+14.5)
=-0.125*100-0.125*50
=-0.125(100+50)
=-0.125*150
=-18.75

=-100*(1/8)-(1/8)*35.5+14.5*(-1/8)
=(1/8)(-100-35.5-14.5)
=1/8*(-150)
=-18.75
