Question 235456
Setup
------
Given: X = 21.5ft / 3
----------------------
Solution
----------------------
I think that it is easier if you convert the feet to inches.
1ft = 12in
So {{{21.5ft * (12in/1ft) = 258in}}}
Now replace the 21.5ft in the given equation with 258in
{{{X = 21.5ft / 3}}}
{{{X = 258in / 3}}} Simplify
{{{X = 86in}}}
or you can convert the 86in back into feet if you want.
{{{X = 86in * (1ft/12in)}}}
{{{X = 7.16667ft}}}
