{{{(red(12_gallons_of_paint))/green(8329ft^2)}}}{{{matrix(3,1,"?",""="",""<>"")}}}{{{(green(9_gallons_of_paint))/red(1240ft^2)}}} 

Cross multiply.  That is, multiply the <font color = "red">red</font> numbers above, then
multiply the <font color = "green">green</font> numbers and if they are equal, then the rates
are equivalent.  If they are not equal, the ratios are not equivalent.

When we multiply the <font color = "red">red</font> numbers we get {{{red(12*1240)=red(14880)}}} 

When we multiply the <font color = "green">green</font> numbers we get {{{green(9*8329)=green(74961)}}}

These are not equal, so we know that the rates are not equivalent.
