Answer :

NO THE FIRST ANSWERS WRONG
9 foot = 9*12 = 108 inches minus 2.5 inches would return the answer 105.5 inches

we know that


[tex] 1 [/tex] ft is equal to [tex] 12 [/tex] in

so

[tex] 9 [/tex] ft is equal to

by proportion

[tex] \frac{1}{12} =\frac{9}{x} \\ \\ x=12*9\\ \\ x=108 [/tex] in


therefore


[tex] 9ft-2\frac{1}{2} in=108 in-2.5 in\\ \\ =105.5 in [/tex]

[tex]105.5 in=105 \frac{1}{2}in[/tex]

the answer is

[tex]105 \frac{1}{2}in[/tex]
