梨樹(shù)的棵數(shù)

，1.5x-x表示

梨樹(shù)比桃樹(shù)多的棵數(shù)

．

Answer 1

分析：桃樹(shù)的棵數(shù)×梨樹(shù)的棵數(shù)是桃樹(shù)的幾倍=梨樹(shù)的棵數(shù)，梨樹(shù)的棵數(shù)-桃樹(shù)的棵數(shù)=梨樹(shù)比桃樹(shù)多的棵數(shù)，據(jù)此解答即可．

解答：解：果園里有桃樹(shù)x棵，梨樹(shù)的棵數(shù)是桃樹(shù)的1.5倍．那么1.5x表示梨樹(shù)的棵數(shù)，1.5x-x表示梨樹(shù)比桃樹(shù)多的棵數(shù)．
故答案為：梨樹(shù)的棵數(shù)，梨樹(shù)比桃樹(shù)多的棵數(shù)．

點(diǎn)評(píng)：此題考查了用字母表示數(shù)的方法，要注意根據(jù)題目中所給的等量關(guān)系列式解答．
