0.56×9.9+0.056怎么巧算-搜答案-智慧作业帮

46.3*0.56+53.8*0.56-0.56*0.1=0.56*（46.3+53.8-0.1）=56明白了吗?

=46.3×0.56+53.8×0.56-0.1×0.56=(46.3+53.8-0.1)×0.56=100×0.56=56

46.3*0.56+5.38+5.6-0.056=46.3*0.56+53.8+0.56-0.56×0.1=（46.3+53.8-0.1）×0.56=100×0.56=56再问：是5.38不是53.8

9.9*99+9.9=9.9*（99+1）=9.9*100=990

5.6×0.38+0.56×4.7+0.056×15，=0.56×3.8+0.56×4.7+0.56×1.5，=0.56×（3.8+4.7+1.5），=0.56×10，=5.6；

46.3*0.56+5.38*5.6-0.056=46.3×0.56+53.8×0.56-0.1×0.56=(46.3+53.8-0.1)*0.56＝100*0.56=56再问：我是5.38，不是53

0.056×0.15列竖式

46.3×0.56+5.38×5.6-0.056=46.3×0.56+53.8×0.56-0.56*0.1=(46.3+53.8-0.1)0.56=56

0.56*99+0.56

56

哦再答：要过程吗再问：要再答：呃呃呃再答：急吗再问：急再答：呃呃我还在吃饭汗-_-||再问：十分钟行吗再答：不急的话先采十分钟后给你再问：我不信再答：……再答：看我的回答再问：你吃完饭了吗再答：差不多

应该是0.56吧.即56美分,fifty-sixcents再问：就是0.056美金，要是0.56美金的话我也知道的再答：那也只能是0.056USD，或者。。5.6cents？再问：我是要报价的，关键是

46.3*0.56+53.8*0.56-0.56*0.1=0.56*（46.3+53.8-0.1）=56明白了吗?

46.3*0.56=(46.3*56)/100=(46.3*7*8)/1005.37*5.6=(5.37*56)/10=(5.37*7*8)/10下面同理

1.原式=46.3*0.56+53.8*0.56-0.1*0.56=（46.3+53.8-0.1）*0.56=100*0.56=562.原式=100+400+700+900+36*4+0.24*4=2

0.56x(3.8+4.7+1.5)=0.56x10=5.6

9.9*5.6+0.56=9.9*0.56*10+0.56=99*0.56+0.56=0.56*(99+1)=0.56*100=56再问：4.4*5.5-44*0.33-0.44*22

0.56×9.9+0.56×0.1=0.56×(9.9+0.1)=0.56×10=5.6

0.5*【9.9-（10-0.56/5.6）】=0.5*【9.9-（10-0.1）】=0.5*（9.9-9.9—）=0.5*0=0

46.1×0.56＋5.38×5.6＋1×0.056＝46.1×0.56＋53.8×0.56＋0.1×0.56＝0.56×（46.1＋53.8＋0.1）＝0.56×100＝56

我查了资料,韩国规定,每100毫升50毫克以上就认定酒驾了,希望摩托车大叔安好,khun尽快走出阴影,大家都要引以为戒,绝对绝对不要酒后驾车,绝对!
