10.8×3.6÷3.2是简便运算吗

10.8*3.6/3.2原式=10.8*9*0.4/(8*0.4)=(10+0.8)*9/8=90/8 + 0.9=11.25 + 0.9=12.15

0.8-10.8÷3.6*1.5=10.8-10.8÷1.2÷3*0.5*3=10.8-10.8÷1.2*0.5=10.8-10.8÷0.4÷3*0.5=10.8-27÷3*0.5=10.8-

原式=10.8*9*0.4/(8*0.4)=(10+0.8)*9/8=90/8 + 0.9=11.25 + 0.9=12.15

86.4*3.2-6.4*3.2=(86.4-6.4)*3.2=80*3.2=256

可以39.68÷3.2*10.1=12.4*(10+0.1)=12.4*10+12.4*0.1=124+1.24=125.24

4.72÷10.6÷3.2-3.6=4.72÷(10.6x3.2)-3.6=4.72÷33.92-3.6=0.14-3.6=-3.46谢谢,请采纳

3.6*333+1.4*666+10.8*111前面是乘以333,中间是乘以666,最后乘以111,我们可以发现:333=3x111,666=6x111所以,3.6*333+1.4*666+10.8*111=3.6x3x111+1.4x6x111+10.8x111=(3.6x3+1.4x6+10.8)x111=(10.8+8.4+10.8)x111=30x111=3330也可以,3.6*333+1.4*666+10.8*111=3.6÷2*2*333+1.4*666+10.8÷6*6*111=1.8*666+1.4*666+1.8*666=(1.8+1.4+1.8)*666=5*666=3330

解: 17.28÷5.4*3.6=3.2*3.6=(3+0.2)*3.6=3*3.6+0.2*3.6=10.8+0.72=11.52

3.6除以[0.25乘以(1.6加3.2)]简便计算3.6除以[0.25乘以(1.6加3.2)]=3.6÷(0.25*4.8)=3.6÷1.2=3

一共两百道,选136道吧2.5*2= 0.5*10= 0.6*8= 2.1*2=2.8*10= 0.7*0.8= 0.04*20= 5.6+0.4=4.7+2.3= 4.5*2= 6.9-2.5= 7.2*0.8= 6*3.4= 0.62-0.32= 1.4*0.5= 0.75*100=0.02*0.5= 3.6*0.3= 6.3÷7= 5.6*100=0.75÷0.25= 0.125*8= 4.8÷0.3= 0.86÷2=0.
