Question

少先隊(duì)員種柳樹(shù)40棵，種的楊樹(shù)的棵數(shù)比柳樹(shù)棵數(shù)的3倍多15棵．少先隊(duì)員種楊樹(shù)和柳樹(shù)共多少棵？

Answer 1

分析：已知種柳樹(shù)40棵，種的楊樹(shù)的棵數(shù)比柳樹(shù)棵數(shù)的3倍多15棵，那么種楊樹(shù)的棵數(shù)為40×3+15，少先隊(duì)員種楊樹(shù)和柳樹(shù)共40+（40×3+15）棵，計(jì)算即可．

解答：解：40+（40×3+15），
=40+（120+15），
=40+135，
=175（棵）；
答：少先隊(duì)員種楊樹(shù)和柳樹(shù)共175棵．

點(diǎn)評(píng)：此題解答的關(guān)鍵是根據(jù)倍數(shù)關(guān)系求出楊樹(shù)的棵數(shù)．
