Question

If a person measures 42in in height what does the person measure in feet. I got the answer correct which is 3ft 6in but I need to show the dimensional analysis part of it ?

Answer 1

$42in=42\cdot0.0833333ft=3.5ft\\\\Answetr\ is\ 3.5\ feet.$

Answer 2

$\frac{42in.}{1} \frac{1ft.}{12in.}$
The inches cancel
$\frac{42}{1} \frac{1ft.}{12}= \frac{42}{12} ft.$
Than reduce to get 3.5ft.
