分析:除數(shù)是小數(shù)的除法:先把除數(shù)的小數(shù)點向右移動若干位,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)點也向右移動相同的位數(shù),然后按著除數(shù)是整數(shù)方法進行計算,商的小數(shù)點要和變化后的被除數(shù)的小數(shù)點對齊.
解答:解:根據(jù)商不變的性質(zhì),
15.7÷0.7=157÷7=22…0.3,
所以,15.7÷0.7 商的最高位在十位.
故答案為:×.
點評:此題考查了小數(shù)除法的計算法則:小數(shù)除法,先移動除數(shù)的小數(shù)點使它變成整數(shù),然后按除數(shù)是整數(shù)除法計算.
