While they may have been called magic squares, there is absolutely nothing magical about them. The arrangement of numbers in magic squares is all very rational.
Here's an idea: Why not simply draw an ordinary 3 x 3 magic square with the numbers 1 through 9, then in each cell, draw a line under the number and add a denominator of 10. Bingo. You have a magic square comprised of the fractions 1/10 through 9/10, and the universal sum is 1.5 instead of 15. Something along those lines.
Stratified: I disagree with stratified, the answer is "simple" arrangement.
