well, the shortest will be 14.1 clearly, and the longest of all three is 15.2.
let's check the ratio from shortest to longest.
[tex]\bf 14.1\implies \cfrac{141}{10}\qquad \qquad\qquad 15.2\implies \cfrac{152}{10}
\\\\\\
\cfrac{shortest}{longest}\qquad 14.1:15.2\qquad \cfrac{14.1}{15.2}\implies \cfrac{\quad \frac{141}{10}\quad }{\frac{152}{10}}\implies \cfrac{141}{10}\cdot \cfrac{10}{152}
\\\\\\
\cfrac{141}{152}[/tex]
