0.25×0.25×0.25×....×0.25×4×4×...×4
(-270)*0.25+0.25*21.5+(-8.5)*(-0.25)=?

(-270)*0.25+0.25*21.5+(-8.5)*(-0.25)=0.25x(-270+21.5+8.5)=0.25x-240=0.25x4x-60=-60

12*222.2-666.6+0.25*0.25*80

12*222.2-666.6+0.25*0.25*80=12*222.2-222.2*3+0.25*0.25*80=222.2*(12-3)+0.25*(80+1)=222.2*9+0.25*81=2

67*0.25+2.5*3.75-4.5*0.25简算

67*0.25+2.5*3.75-4.5*0.25=67×0.25+0.25×37.5-4.5×0.25=(67+37.5-4.5)×0.25=100×0.25=25

0.75+0.075÷0.25+0.25

0.75+0.075÷0.25+0.25=0.75+0.075x4+0.25=0.75+0.3+0.25=0.75+0.25+0.3=1+0.3=1.3

0.75-0.25+0.75-0.25的 简便计算

你好!是这样算的:(0.75+0.75)-(0.25+0.25)=1.5-0.5=1

0.25*39+0.25 简便计算

0.25*39+0.25=0.25×(39+1)=0.25×40=10

12*222.2-666.6+0.25*0.25*80简算

12*222.2-666.6+0.25*0.25*80=222.2*(12-3)+80/(4*4)=222.2*9+5=2222-222.2+5=2004.8

7.69*101 0.25*39+0.25 简便运算

7.69*101=7.69*(100+1)=7.69*100+7.69*1=769+7.69=776.690.25*39+0.25=0.25*(39+1)=0.25*40=10

3.67+0.25-3.67+0.25如何化简?!?!

3.67+0.25-3.67+0.25=(3.67-3.67)+(0.25+0.25)=0+0.5=0.5

用简便方法计算:0.25*39*0.25

0.25×39+0.25=1/4×(39+1)=0.25×40=100.25×39×0.25=1/4×1/4×39=1/16×39=39/16

0.25*0.5/0.25*8.2的简便运算

0.25*0.5/0.25*8.2=0.5*8.2=4.1

0.25*2.8=0.25*(4*0.7)

应该是拆分.其实不用这种题目不一定要用简便方法做,只要你觉得准确,什么方法都好.

x-0.25=0.25x

x-0.25=0.25x化为x-0.25x=0.25即0.75x.=0.25所以x=0.25/0.75=1/3=0.333333

0.25,0.25,0.5,2,16,()

设最后一个数是x相邻的两个数,用后一个除以前一个得:1,2,4,8,x/16(*)(*)中前四个数,后一个是前一个的2倍,则得x/16=8*2得x=256像这种推理题,不同的思维方式得出的结果可能也不

0.25 0.25 0.25 0.25等于0.125

0.25*0.25/(0.25+0.25)

计算一道数学题,(-370)×(-0.25)+0.25×24.5+(-5.5)×(-0.25)

分析:其实这题的关键在于要先把原来的式子变个样子就可以了.我们都知道两个负数相乘的结果是正数,所以在计算时可以把两个负数相乘的式子当中的负号去掉,这样就迎刃而解了.第一步:先变化一下原来的式子(-37

0.25×8.19-0.25×4.19

0.25×8.19-0.25×4.19=0.25×(8.19-4.19)=0.25×4=1所以答案是1

41*0.25-0.25+0.25*60 简便计算

41×0.25-0.25+0.25×60=0.25×﹙41-1+60﹚=0.25×100=25

0.25*0.8+0.2*0.25-0.25的简便算法

运用乘法分配律来计算(0.25=0.25*1)0.25*0.8+0.2*0.25-0.25=0.25*(0.8+0.2-1)=0.25*0=0
