Given:
The given numbers are 1.25, (-3/2), -1.25, 1(1/2).
The objective is to arrange the numbers from least to greatest.
Explanation:
The numbers can be converted into decimal as,
[tex]\begin{gathered} -\frac{3}{2}=-1.5 \\ 1\frac{1}{2}=\frac{2+1}{2}=\frac{3}{2}=1.5 \end{gathered}[/tex]
So, the numbers are 1.25, -1.5, -1.25 and 1.5.
Now, plot the numbers on the number line.
By considering the number line above, the order of least to greatest are,
[tex]-\frac{3}{2},-1.25,1.25,1\frac{1}{2}[/tex]
Hence, the required order of the numbers are obtained.
