Question 924289
Well, first, I'd draw a rectangle.

Next I would divide it into fourths.

*[illustration rectangle1.bmp].

Now divide one of the fourths into half.

*[illustration rectangle2.bmp].

Then color in one of those halves.

*[illustration rectangle3.bmp].

This is a representation of coloring in {{{1/2}}} of {{{1/4}}} of a rectangle.
