24.3%4.5+3.2x0.8怎么简算

24.3%4.5+3.2x0.8怎么简算 24.3%4.5+3.2x0.8 =24.3÷4.5+3.2*0.8 =5.4+2.56 =7.96

24.3除以4.5加3.2乘以0.8怎样简便就怎样算 24.3除以4.5加3.2乘以0.8 =5.4+2.56 =7.96 直接计算

可以3.2÷0.25x125x0.8=(3.2÷0.25)×(125×0.8)=12.6×100=1260

(3.2+0.56)÷0.8 =3.2÷0.8+0.56÷0.8 =4+0.7 =4.7 简便计算是一种特殊的计算,它运用了运算定律与数字的基本性质,从而使计算简便,使一个很复杂的式子变得很容易计算出得数。 在数的运算中,有加(+)、减(-)、乘(×)、除(÷)四种运算,我...

解:原式=1.25×0.8×0.32 =1×0.32 =0.32 望采纳

=3.2×0.2+0.2×4 =0.2×(3.2+4) =0.2×7.2 =1.44

=3.2×8+6.8×8 =(3.2+6.8)×8 =10×8 =80

共有34种方法! 2*(3*8-12)=24 2*3*(12-8)=24 2*(8*3-12)=24 2*(8+12/3)=24 2*(12/3+8)=24 2*(12-8)*3=24 3/2*8+12=24 3*2*(12-8)=24 3*8/2+12=24 (3*8-12)*2=24 3*(12-8)*2=24 3*(12-8/2)=24 8/2*3+12=24 (8-2*3)*12=24 (8-2)/3*12=24 (8-2)*12...

101x2.3-1.25x2.3x0.8=101x2.3-1.25x0.8x2.3=101x2.3-1x2.3=(101-1)x2.3=100x2.3=230

3.2x5.4+54x0.68 =3.2x5.4+5.4x6.8 =(3.2+6.8)x5.4 =10x5.4 =54 3.2x5.4+54x0.68 =0.32x54+54x0.68 =(0.32+0.68)x54 =1x54 =54
