The front side of a square sheet of paper $ABCD$ is red, and the back side is white. $E$ and $F$ divide diagonal $AC$ into three equal parts, with $E$ lying closer to $A$. The sheet is folded along lines perpendicular to $AC$ by folding the back side towards the front (that is, making the back of the sheet appear on top). During the first folding, point $A$ is moved to cover $F$, and during the second folding, point $C$ is moved to cover $E$. What will be the ratio of the red area to the white area on the front side of the sheet in the end?
