## 数学代写|代数学代写Algebra代考|FRACTIONS IN THE REAL WORLD: MEASURING

Understanding fractions in the real world is a two-way street. Not only do you have to be able to take a fraction and cut, pour or draw it, but you have to be able to go the other way too. If the cutting, pouring or drawing has already been done, you need to be able to “say what the fraction is” – which really comes down to measuring.

Example: The picture below represents a candy bar, with the shaded portion representing the amount that a kid ate.
a) Approximately, how many $8^{\text {ths }}$ of the candy bar did the kid eat?
Solution: Divide the candy bar into 8 equal pieces. (You can put your dividing lines at the bottom of the bar so the picture doesn’t get too messy or you can draw a number bar right under it.)
Either way, you can see: The kid ate about $\frac{5}{8}$ of the candy bar.
b) Approximately, what percent of the candy bar did the kid eat?

Imagine eating $\frac{1}{8}$ of a candy bar or $\frac{3}{8}$ of a candy bar or $\frac{7}{8}$ of a candy bar. No big deal, once you know what those numbers mean. But what would it mean to eat $\frac{0}{8}$ of a candy bar or $\frac{8}{8}$ of a candy bar? Well, $\frac{0}{8}$ would mean that you didn’t eat any of the candy bar, while $\frac{8}{8}$ would mean that you ate the whole thing. Look at the bars:
But let’s talk numbers. Not eating any of the candy bar would mean you ate $\underline{0 \text { candy bars. }}$. Eating the whole thing would mean that you ate 1 whole candy bar – Wait! Stop with the word “whole”. It’s not necessary. Just talk numbers! Eating the whole thing would mean that you ate 1 candy bar.
So, $\frac{0}{8}=0$ and $\frac{8}{8}=1$.

a)大约，这个孩子吃了多少$8^{\text {ths }}$的糖果棒?解决方法:将糖果棒分成8等份。(你可以在条形图的底部画分界线，这样图片就不会太乱，或者你可以在它的正下方画一个数字条形图)

b)大约，孩子吃了多少块糖果?

So, $\frac{0}{8}=0$ and $\frac{8}{8}=1$ .

## MATLAB代写

MATLAB 是一种用于技术计算的高性能语言。它将计算、可视化和编程集成在一个易于使用的环境中，其中问题和解决方案以熟悉的数学符号表示。典型用途包括：数学和计算算法开发建模、仿真和原型制作数据分析、探索和可视化科学和工程图形应用程序开发，包括图形用户界面构建MATLAB 是一个交互式系统，其基本数据元素是一个不需要维度的数组。这使您可以解决许多技术计算问题，尤其是那些具有矩阵和向量公式的问题，而只需用 C 或 Fortran 等标量非交互式语言编写程序所需的时间的一小部分。MATLAB 名称代表矩阵实验室。MATLAB 最初的编写目的是提供对由 LINPACK 和 EISPACK 项目开发的矩阵软件的轻松访问，这两个项目共同代表了矩阵计算软件的最新技术。MATLAB 经过多年的发展，得到了许多用户的投入。在大学环境中，它是数学、工程和科学入门和高级课程的标准教学工具。在工业领域，MATLAB 是高效研究、开发和分析的首选工具。MATLAB 具有一系列称为工具箱的特定于应用程序的解决方案。对于大多数 MATLAB 用户来说非常重要，工具箱允许您学习应用专业技术。工具箱是 MATLAB 函数（M 文件）的综合集合，可扩展 MATLAB 环境以解决特定类别的问题。可用工具箱的领域包括信号处理、控制系统、神经网络、模糊逻辑、小波、仿真等。
