刻度尺从5到多少是4厘米？

刻度尺是一种常见的测量工具，用于准确测量长度或距离。当我们需要在刻度尺上找到特定长度时，我们通常会看到不同的刻度和数字，用于表示不同的单位和值。那么，在这个问题中，我们要找的是从5开始，到哪个位置才能达到4厘米。

首先，让我们回顾一下刻度尺的基本知识。一般来说，刻度尺上的最小刻度代表着一定的单位长度，比如厘米或者毫米。在一般的刻度尺上，最小刻度往往是1毫米。这意味着，如果我们要测量4厘米长度，我们需要移动刻度尺上的四个单位，即移动到距离5开始的第4个单位。

所以，答案就是9。从刻度尺上的5开始，移动四个单位，我们就可以到达4厘米的位置。

How far is it from 5 to reach 4 centimeters on the ruler?

The ruler is a common measuring tool used to accurately measure length or distance. When we need to find a specific length on a ruler, we usually see different scales and numbers that represent different units and values. So, in this question, we want to know how far we have to go from the starting point of 5 to reach 4 centimeters.

Firstly, let's review some basic knowledge about rulers. Generally, the smallest scale on a ruler represents a certain unit length, such as centimeters or millimeters. On a standard ruler, the smallest scale is often 1 millimeter. This means that if we want to measure a length of 4 centimeters, we need to move the ruler by four units, which is the fourth unit from the starting point of 5.

Therefore, the answer is 9. Starting from 5 on the ruler, moving four units will bring us to the position representing 4 centimeters.
