Question

15．兩個數(shù)的差是238，如果減數(shù)是327，則被減數(shù)是565；如果被減數(shù)是327，則減數(shù)是89．

Answer 1

分析 被減數(shù)-減數(shù)=差，被減數(shù)=減數(shù)+差，減數(shù)=被減數(shù)-差，據(jù)此解答即可．

解答 解：差是238，如果減數(shù)是327，則被減數(shù)是：
327+238=565

如果被減數(shù)是327，減數(shù)是：
327-238=89
故答案為：565，89．

點評 此題主要考查了被減數(shù)、減數(shù)、差的關(guān)系：被減數(shù)-減數(shù)=差，被減數(shù)=減數(shù)+差，減數(shù)=被減數(shù)-差．
