2.4×2点6 0点24×3点一的简便运算

2.4X2.6+0.24X3.1=2.4X(2.6+0.31)=2.4X2.91=2.4X3-2.4X0.09=7.2-0.216=7-0.016=6.984

2.4*2.69+0.24*3.1=2.4*2.69+2.4*0.31=2.4*(2.69+0.31)=2.4*3=7.2

2.4*2.5x3.78 =(0.4*2.5)*6*3.78 =6*3.78 =6*4-6*0.22 =24-1.32 =22.68

9点6除以(0点24乘3点2) =9.6÷3.2÷0.24=3÷0.24=300÷24=100÷8=12.5

24*0.62+2.4*3 = 22.082.4x3.5十65x0.24简便用算2.4x3.5+65x0.24=2.4x3.5+6.5x2.4=2.4x(3.5+6.5)=2.4x10=24

2.4*0.25=(0.6*4)*0.25=0.6*(4*0.25)=0.6*1=0.6

24*896÷24=(24÷24)*896=896 你是小学的吧!o(∩_∩)o~

二点3*1点4+2点3*8点6-0点3*23=2.3*(1.4+8.6-3)=2.3*(10-3)=23-6.9=16.31.

0.36+0.64*0.65=0.36+0.32*2*0.65=0.36+0.32*1.3=0.04*(9+8*1.3)=0.04*(9+10.4)=0.04*19.4=0.776

(2.4+3.6)X0.5=2.4X0.5+3.6X0.5=1.2+1.8=3望采纳
