一、笔算下面各题.221×16307×26183×15135×2458×912408×25315×47508×15二、列式计算.123的35倍是多少?13个450相加得多少?三、两个因数分别是72和8

8.7×17.4-8.7×7.4=12.5×0.4×2.5×8=0.68÷（5.2-3.5)×1.25=(0.25+2.5+25)×0.4=5-0.9×0.2+1.8÷0.5=6.4×3.28+4.6

17×40＝680,100－63＝37,3.2＋1.68＝4.88,2.8×0.4＝1.1214－7.4＝6.6,1.92÷0.04＝48,0.32×500＝160,0.65＋4.35＝510－5.4

小小年纪不要偷懒学习还是为自己学的

145×12＝1740

答题的太累了,你去百度文库找找吧!别忘点赞同.——很重要的!

是小数×小数,还是小数×整数多着呢1.5×3.24.2×0.84.6×0.23.6×2.82.3×43.7×26.4×35.1×4

我建议你去买一本《重点难点》或《数学详细解析》石龙购书中心应该有,去看一下吧!我给你出几道,你做一下：5*2.5=8*1.25=1.26*5.28=3.5*10.01=20*5.8=58*225.2=

题目呢,你不把题目给我,再问：我只用算数

那你要什么再问：小数或整数啊
