Answer
$1\frac{1}{8}$ inches, $1.25$ inches, $1\frac{3}{8}$ inches, $1.5$ inches, $1\frac{9}{16}$ inches
Work Step by Step
Putting all the decimals/fraction in one format with one denominator is an easy way to clearly see the smallest to largest spectrum.
For example 1.5 can be written as $1\frac{8}{16}$ and $1\frac{1}{8}$ can be written as $1\frac{2}{16}$.
