Question

被減數(shù)與減數(shù)的比是3：2，被減數(shù)是減數(shù)的________，差是減數(shù)的________．

Answer 1

    
分析：被減數(shù)與減數(shù)的比是3：2，說(shuō)明被減數(shù)是3份，則減數(shù)就是2份，差=被減數(shù)-減數(shù)=1；要求被減數(shù)是減數(shù)的幾分之幾，用被減數(shù)除以減數(shù)；差是減數(shù)的幾分之幾，用差除以減數(shù)；即可得解．
解答：由被減數(shù)：減數(shù)=3：2，得
如果被減數(shù)=3份，
則減數(shù)=2份，
差=被減數(shù)-減數(shù)=1，
所以被減數(shù)÷減數(shù)=3÷2=，
差÷減數(shù)=1÷2=，
答：被減數(shù)是減數(shù)的，差是減數(shù)的；
故答案為：，．
點(diǎn)評(píng)：關(guān)鍵是根據(jù)比例，假設(shè)出被減數(shù)和減數(shù)，進(jìn)而求出差，按照要求來(lái)解決問(wèn)題．
