Chapter 10.1, Problem 43E
On National Public Radio, the "Weekend Edition" program on Sunday, July 29, 2001, posed the following puzzle: Draw a three-by-three square (three boxes across by three boxes down). Put the fraction 3/8 in the first square in the first row. Put the fraction 1/4 in the last square in the second row. The object is to put a fraction in each of the remaining boxes, so the three numbers in each row, each column, and each of the long diagonals add up to I. Solve this puzzle by letting seven variables represent the seven unknown fractions, writing eight equations for the eight sums, and solving by the Gauss-Jordan method.
