“3.8x9.9”怎样简便计算? -
3.8X9.9＝3.8X（10一0.1）＝3.8X10一3.8X0.1＝38一0.38＝37.62
37.62-16.25-13.75 =37.62-（16.25+13.75）37.62-30 =7.62
99X0.38简便计算。 -
99×0.38 ＝（100-1）×0.38 ＝100×0.38-1×0.38 ＝38-0.38 ＝37.62
3.8X4.5+3.8X5.6-0.38 =0.38×45+0.38×56-0.38.=0.38×(45+56-1)=0.38×100 =38.
9.9x3.8的简便计算 -
9.9x3.8 =(10-0.1)x3.8 =38-0.38 =37.62 希望帮到你望采纳谢谢，
运用乘法分配律进行简算3.8*9.9+0.387 =3.8*(10-0.1)+0.387 =38-0.38+0.38+0.007 =38.007
