For this case what we should do is to rewrite the mixed numbers as fractions and then as decimals.
Writing the mixed numbers as fractions we have:
[tex]1\frac{1}{8}=\frac{8+1}{8} = \frac{9}{8}[/tex]
[tex]1\frac{1}{4}=\frac{4+1}{4} = \frac{5}{4}[/tex]
[tex]\frac{1}{2}=\frac{1}{2}[/tex]
We now write the fractions as decimals.
We have then:
[tex]\frac{9}{8} = 1.125[/tex]
[tex]\frac{5}{4} = 1.25[/tex]
[tex]\frac{1}{2} = 0.5[/tex]
