Question 147945
{{{4/12=n/26}}}  Cross multiply and get {{{4(26)=12(n)}}}.  Multiply it out and get {{{104=12n}}}.  Then divide each side by 12 and get {{{104/12=n}}}.  This reduces to {{{26/3=n}}} or {{{8.66667}}}.

As a shortcut you know that 12 divided by 3 is 4, so divide 26 by 3 and get 8.66667.
