植树问题是一类有趣的数学问题,是指在一定的线路上,根据总路程、间隔长以及要植树的棵数来进行思考、计算的问题。最常见的有三类情况:1.两端都植:距离÷间隔长+1=棵数2.只植一端:距离÷间隔长=棵数3.两端都不植:距离÷间隔长-1=棵数【例1】有一条路长100米,在路的一侧从头到尾每隔10米栽一棵树。一共可栽多少棵树?
Tree planting problem is a kind of interesting math problems, refers to a certain line, according to the total distance, long intervals and the number of trees to be planted for thinking and calculation of the problem. The most common are three types of situations: 1. Both ends are planted: distance ÷ interval length + 1 = number of trees 2. Only plant one end: distance ÷ interval length = number of trees 3. No planting at both ends: distance ÷ interval length -1 = Number of trees 【Example 1】 One of the roads is 100 meters long, and a tree is planted every 10 meters on the side of the road. How many trees can be planted?
