0.072×0.25竖式怎么来算

0.072*0.15竖式如图:扩展资料小数乘小数的计算方法:(1)先把小数扩大成整数.(2)按整数乘法的法则算出积.(3)再看因数中一共有几位小数,就从积的右边起数出几位点上小数点.乘得的积的小数位数不够时,要在前面用0补足再点小数点.注意:计算结果中,小数部分末尾的0要去掉,把小数化简;小数部分位数不够时,要用0占位.

64x(12.5+0.25+0.5) =8*(8*12.5+8*2.5+8*0.5) =8*(100+20+4) =8*(125-1) =1000-8 =992

把0.25和0.03的末位对齐,然后按照整数乘法计算,最后点4位小数.答案是0.0075.

=0.0108

=(4+0.8)*0.25 =1+0.2 =1.2

0.48*0.25=0.48/4=0.120.072*1.25=0.072/0.8=0.09

13.08*0.25--------- 65402616-----------32700

0.25*25.96怎样算竖式计算=0.25x(26-0.04)=0.25x26-0.25x0.04=6.5-0.01=6.49

7.54/0.25=30.16;验算30.16*0.25=70.54

3.25*9.04=3.25*9+3.25*0.04=3*9+0.25*9+3*0.04+0.25*0.04=27+2.25+0.12+0.01=29.38
