Question

7.84÷0.56時(shí)，先將除數(shù)0.56的小數(shù)點(diǎn)向________移動(dòng)________位，使它變成________，再將除數(shù)7.84的小數(shù)點(diǎn)也向________移動(dòng)________位，最后按除數(shù)是________的除法進(jìn)行計(jì)算．

Answer 1

右    2    整數(shù)    右    2    整數(shù)
分析：本題根據(jù)除數(shù)是小數(shù)的小數(shù)除法的運(yùn)算法則分析填空即可，除數(shù)是小數(shù)的小數(shù)除法法則：先看除數(shù)中有幾位小數(shù)，就將除數(shù)的小數(shù)點(diǎn)向右移動(dòng)幾位，將除數(shù)化成整數(shù)，然后再把被除數(shù)的小數(shù)點(diǎn)向右移動(dòng)幾位，數(shù)位不夠的用零補(bǔ)足； 然后按照除數(shù)是整數(shù)的小數(shù)除法來(lái)除．
解答：根據(jù)除數(shù)是小數(shù)的小數(shù)除法的運(yùn)算法則可知，
計(jì)算7.84÷0.56時(shí)，先將除數(shù)0.56的小數(shù)點(diǎn)向右移動(dòng)2位，使它變成整數(shù)，
再將除數(shù)7.84的小數(shù)點(diǎn)也向右移動(dòng)2位，最后按除數(shù)是整數(shù)的除法進(jìn)行計(jì)算．
故答案為：右，2，整數(shù)，右，2，整數(shù)．
點(diǎn)評(píng)：本題通過(guò)具體算式考查了學(xué)生對(duì)除數(shù)是小數(shù)的小數(shù)除法的運(yùn)算法則的理解與應(yīng)用．
