Question

列豎式計(jì)算，并驗(yàn)算．
60.5×0.33=
13.24×0.25=
43.7×7.4=

Answer 1

分析：根據(jù)小數(shù)乘法的計(jì)算法則：先按照整數(shù)乘法法則算出積，再看因數(shù)中一共有幾位小數(shù)，就從積的右邊向左數(shù)出幾位，點(diǎn)上小數(shù)點(diǎn)．據(jù)此計(jì)算．

解答：解：60.5×0.33=19.965；


13.24×0.25=3.31；


43.7×7.4=323.38；

點(diǎn)評(píng)：此題考查的目的是理解掌握小數(shù)乘法的計(jì)算法則，并且能夠正確熟練地進(jìn)行計(jì)算．
