分析:被除數(shù)是三位數(shù),除數(shù)是兩位數(shù);因為被除數(shù)的前兩位數(shù)字如果大于或等于除數(shù),則商是兩位數(shù),如果小于除數(shù),則商是一位數(shù),由此即可解答.
解答:解:算式754÷25,被除數(shù)的前兩位數(shù)字75大于除數(shù)25,所以商是兩位數(shù);
算式748÷82,被除數(shù)的前兩位數(shù)字74小于除數(shù)82,所以商是一位數(shù);
故答案為:兩,一.
點評:解決此題關(guān)鍵是理解被除數(shù)是三位數(shù),被除數(shù)的前兩位數(shù)字大于或等于除數(shù),商是兩位數(shù);小于除數(shù),商就是一位數(shù).
