除數(shù)是小數(shù)的小數(shù)除法二

1、除數(shù)是小數(shù)的除法,蘇教版五年級數(shù)學(xué)上,除數(shù)的小數(shù)點(diǎn)向右移動幾位，被除數(shù)的小數(shù)點(diǎn)也向右移動幾位。,除數(shù)是小數(shù)的除法,先移動除數(shù)的小數(shù)點(diǎn)，使它變成整數(shù)。,然后按照除數(shù)是整數(shù)的小數(shù)除法進(jìn)行計算。,一、口算：4.2÷0.6 = 0.35÷0.07= 0.3÷0.5=5.6÷0.8= 14.7÷0.7=,7,5,0.6,7,21,總價÷單價=數(shù)量,2,5

2、,,·,0,0,0,1,7,5,5,·,,,·,·,0,1,2,千克,答：媽媽買了2千克蘿卜。,除數(shù)的小數(shù)點(diǎn)向右移動幾位，被除數(shù)的小數(shù)點(diǎn)也向右移動幾位。,除數(shù)是小數(shù)的除法,先移動除數(shù)的小數(shù)點(diǎn)，使它變成整數(shù)。,然后按照除數(shù)是整數(shù)的小數(shù)除法進(jìn)行計算。,（位數(shù)不夠的，在被除數(shù)的末尾用“0”補(bǔ)足）,0.16 ）9 .6 6.8 ）34 0.25 ）5,,,,,,0,,0,,0

3、0,,,6,9 6,,0,0,5,340,,0,2,50,,0,0,練一練：先說出下面各題怎樣移動小數(shù)點(diǎn)，再計算。,練一練：括號里填上適當(dāng)?shù)臄?shù),3.7÷0.4= （ ）÷43.7÷0.04= （ ）÷43.7÷0.004= （ ）÷40.042÷0.35= （ ）÷350.42÷0.
