一個三位數(shù)除以23時,淘氣把被除數(shù)看錯了,結(jié)果商得36,余數(shù)為17;正確的被除數(shù)比被看的被除數(shù),還要大29,那么正確的被除數(shù)是________,正確的商應(yīng)是________.
874 38
分析:先將錯就錯,根據(jù)“商×除數(shù)+余數(shù)=被除數(shù)”求出錯誤的被除數(shù),進而根據(jù)“正確的被除數(shù)比被看的被除數(shù),還要大29”,用錯誤的被除數(shù)加上29即可求出正確的被除數(shù),然后根據(jù)“被除數(shù)÷除數(shù)=商…余數(shù)”解答即可.
解答:①36×23+17,
=828+17,
=845,
845+29=874;
②874÷23=38;
答:正確的被除數(shù)是874,正確的商應(yīng)是38;
故答案為:874,38.
點評:解答此題的關(guān)鍵:根據(jù)在有余數(shù)的除法中,根據(jù)被除數(shù)、除數(shù)、商和余數(shù)四個量之間的關(guān)系進行解答即可.
