Question

用豎式計(jì)算．

7.62÷3=	0.36×0.71=	0.544÷16=
0.4×7.25=	0.54×4.8=	89.6÷3.5=

Answer 1

分析：根據(jù)小數(shù)的乘法的計(jì)算法則和小數(shù)除法的計(jì)算法則進(jìn)行計(jì)算，應(yīng)注意求商時(shí)，商的小數(shù)點(diǎn)與被除數(shù)的小數(shù)點(diǎn)對(duì)齊．

解答：解：①7.62÷3=2.54


②0.36×0.71=0.2556


③0.544÷16=0.034


④0.4×7.25=2.9


⑤0.54×4.8=2.592


⑥89.6÷3.5=25.6

點(diǎn)評(píng)：本題考查了小數(shù)的乘除法，運(yùn)用小數(shù)乘除法的計(jì)算法則進(jìn)行計(jì)算，注意正確確定小數(shù)的位數(shù)以及小數(shù)點(diǎn)的位置．
