Question

計(jì)算小數(shù)乘法，不必把小數(shù)點(diǎn)對齊．

√

．（判斷對錯）

Answer 1

分析：根據(jù)小數(shù)乘法的計(jì)算法則，先按照整數(shù)乘法的計(jì)算法則算出積，再看兩個因數(shù)一共有幾位小數(shù)，就從積的右邊起數(shù)出幾位點(diǎn)上小數(shù)點(diǎn)．據(jù)此判斷．

解答：解：根據(jù)小數(shù)乘法的計(jì)算法則得，計(jì)算小數(shù)乘法，不必把小數(shù)點(diǎn)對齊．此說法正確．
故答案為：√．

點(diǎn)評：此題考查的目的是理解掌握小數(shù)乘法的計(jì)算法則．
