33 6 5 3 23 2 26 9 9 3
分析:①求被除數(shù),根據(jù):被除數(shù)=商×除數(shù)+余數(shù),進(jìn)行解答;
②求除數(shù),根據(jù):被除數(shù)=商×除數(shù)+余數(shù),可得:除數(shù)=(被除數(shù)-余數(shù))÷商;
③根據(jù)余數(shù)總比除數(shù)小,余數(shù)是4,除數(shù)至少是5,然后試填即可;
④根據(jù)余數(shù)總比除數(shù)小,除數(shù)是3,余數(shù)可以是1或2,然后選擇一個(gè)即可;
⑤根據(jù)余數(shù)總比除數(shù)小,余數(shù)是8,除數(shù)至少是9,然后填寫即可;
⑥根據(jù)余數(shù)總比除數(shù)小,余數(shù)是5,除數(shù)至少是6,然后試填即可.
解答:
解:33÷6=5…3 | 47÷6=7…5 | 19÷5=3…4 |
23÷3=7…2 | 26÷9=2…8 | 32÷9=3…5 |
故答案為:33,6,5,3,23,2,26,9,9,3.
點(diǎn)評(píng):此題應(yīng)根據(jù)被除數(shù)、除數(shù)、余數(shù)和商之間的關(guān)系進(jìn)行解答.
