Algebraic division question

  1. Oct 29, 2011 #1
    Hello, I can't understand where the '2' came from in this equation.

    5x^2y / 10xy^3
    =
    x/2y^2

    I can see how the other values were calculated but the '2' before the y^2 is puzzling me.
    Thanks for any clarification.

    [itex]5x^2y[/itex] and [itex]10xy^3[/itex] both have a common factor [itex]5xy[/itex]. Try factorising now.
