Question

0.056×0.14的積有5位小數(shù)．

√

（判斷對錯(cuò)）

Answer 1

分析：根據(jù)小數(shù)乘法的計(jì)算法則，積的小數(shù)位數(shù)等于兩個(gè)因數(shù)小數(shù)位數(shù)之和．

解答：解：0.056是3位小數(shù)，0.14是2位小數(shù)，所以0.056×0.14的積有5位小數(shù)．
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，明確：積的小數(shù)位數(shù)等于兩個(gè)因數(shù)小數(shù)位數(shù)之和．
