Question

【題目】直接寫得數(shù)

3.6÷0.6= 6.4÷0.8= 5.5÷1.1=

5.6÷8= 4.2÷3= 8.4÷0.21=

2.1÷0.3= 0÷1.5= 9.3÷3= 9.8÷14=

Answer 1

【答案】6 8 5 0.7 1.4 40 7 0 3.1 0.7

【解析】

除數(shù)是小數(shù)的除法計算法則：先移動除數(shù)的小數(shù)點，使它變成整數(shù)，除數(shù)的小數(shù)點向右移動幾位，被除數(shù)的小數(shù)點也向右移動幾位（位數(shù)不夠的補(bǔ)“0”），然后按照除數(shù)是整數(shù)的除法法則進(jìn)行計算；除數(shù)是整數(shù)的小數(shù)除法計算法則：先按照整數(shù)除法的法則去除，商的小數(shù)點要和被除數(shù)的小數(shù)點對齊；如果除到被除數(shù)的末尾仍有余數(shù)，就在余數(shù)后面添“0”，再繼續(xù)除，據(jù)此解答.
