Question

Which of the following lists is not in order from smallest to largest?

Answer 1

Option B

2.33, 1.87, 3.6, 7.1

Step-by-step explanation

To solve this, we will treat each option separately and put them in fraction form and compare the numerators:

OPTION A

`\begin{gathered} 10.1,\text{ 10.5, 11.2, 11.9} \\ \Rightarrow\text{ }(101)/(10),\text{ }(105)/(10),\text{ }(112)/(10),(119)/(10) \end{gathered}`

We see that the numerators are arranged from smallest to largest

OPTION B

`\begin{gathered} 2.33,1.87,3.6,7.1\text{ } \\ \Rightarrow\text{ }(233)/(100),\text{ }(187)/(100),\text{ }(360)/(100),\text{ }(710)/(100) \end{gathered}`

As we can see, 187 is less than 233 and so this option is not arranged in order of smallest to largest
