Question 640578
What you do is actually divide {{{5}}} by {{{24}}}, so {{{0.20833333333333333333333333333333}}}is inside the house. Then, round it to two decimals and you get {{{0.21}}}. 
Next, you move the decimal over two spaces and you get {{{21.0}}}. Then, you throw a % sign at the end to get {{{21.0}}}% or {{{21}}}%
