Length of first bar = 1.75.
Length of second bar = [tex]1\frac{7}{12}[/tex]
Length of third bar = [tex]1\frac{2}{3}[/tex].
Let us convert [tex]1\frac{7}{12} \ and \ 1\frac{2}{3} \ in \ decimals.[/tex]
[tex]\frac{7}{12}=0.5833[/tex]
Therefore, [tex]1\frac{7}{12} = 1.5833[/tex]
[tex]1\frac{2}{3} = 1.667[/tex]
We can see that 1.75 is the longest out of 1.5833 and 1.667.
Therefore, length of longest bar is 1.75 feet.
