[75%(26 44)]*12的简便计算方法是

75×12简便计算 75×12=75x(10+2)=75x10+75x2=750+150=900

原式 =26x64+75x12 =(1+25)x64+25x3x12 =1x64+25x64+25x36 =64+25x(64+36) =64+25x100 =64+2500 =2564 供参考。

75×12÷75×12 =(75÷75)x12x12 =1x144 =144

(75+360)÷(35-12)用简便方法计算 (75+360)÷(35-12) =435÷23 =435/23

解如图。

原式=6/1*4/3 =8/1

解: 32×(75%+50%+12.5%) =32×( 3/4 +1/2 + 1/8) =32×3/4 + 32×1/2 + 32×1/8 乘法分配律 =24+16+4 =44

1)25%*132+1/4*8 2)32*0.125*25 =1/4*132+1/4*8 =(4+8)*0.125*25 =1/4*(132+8) =(4*25)*(8*0.125) =1/4*140 =100*1 =35 =1000 3)75%*76+25*4+0.75*12 =3/4*76+3/4*12+25*4 =3/4*88+100 =166 4)3200*1/8÷2/5+1270 5)(2/3+4/5)*7/6 =400*5/2+1270...

12.75除以(14.6减(1.3加8.2)) =12.75÷(14.6-9.5) =12.75÷5.1 =2.5
