Answer:
Explanation:
We are given the following numbers:
3, 0.075, 0.75%, 4.20
We have to arrange them in order from least to greatest.
First we convert 0.75% in number format.
![0.75\% = \displaystyle(0.75)/(100) = 0.0075](https://img.qammunity.org/2019/formulas/mathematics/middle-school/c3dqvhz081hdgm5w80xol77cgie6s3doiy.png)
Thus, the numbers arranged in order from least to greatest is:
![0.0075 < 0.075 < 3 < 4.20](https://img.qammunity.org/2019/formulas/mathematics/middle-school/mqntqgyxh2mt011zua5fvi71228xqyvzkv.png)
Arrangement:
![0.75\% < 0.075 < 3 < 4.20](https://img.qammunity.org/2019/formulas/mathematics/middle-school/17v1qqb86q1qlulxxxjhscscx1lz8bsvoa.png)
