The table shows the amount of time four students practiced the trumpet one day.

let's convert mixed numbers to fractions for ease:
[tex]\begin{gathered} \text{Cole}=1\cdot\frac{2}{3}=\frac{5}{3}=1.667 \\ \text{Gus}=1\cdot\frac{1}{2}=\frac{3}{2}=1.5 \\ \text{Ryan}=1\cdot\frac{1}{4}=\frac{5}{4}=1.25 \\ \text{Jacob}=1\cdot\frac{7}{12}=\frac{19}{12}=1.583 \end{gathered}[/tex]As you can see:
1.25<1.5<1.583<1.667
Ryan < Gus < Jacob < Cole
