# Q.3 In a “magic square” the sum of number in each row, in each column and along the diagonals is the same. Is this a magic square?

Along first row = $$\frac{4}{11}+\frac{9}{11}+\frac{2}{11} =\frac{15}{11}$$
Along second row = $$\frac{3}{11}+\frac{5}{11}+\frac{7}{11}=\frac{15}{11}$$
Along third row = $$\frac{8}{11}+\frac{1}{11}+\frac{6}{11}=\frac{15}{11}$$
Along first column= $$\frac{4}{11}+\frac{3}{11}+\frac{8}{11}=\frac{15}{11}$$
Along second column= $$\frac{9}{11}+\frac{5}{11}+\frac{1}{11}=\frac{15}{11}$$
Along third column= $$\frac{2}{11}+\frac{7}{11}+\frac{6}{11}=\frac{15}{11}$$
Along first diagonal= $$\frac{4}{11}+\frac{5}{11}+\frac{6}{11}=\frac{15}{11}$$
Along second diagonal= $$\frac{2}{11}+\frac{5}{11}+\frac{8}{11}=\frac{15}{11}$$
Since, the sum of all the fraction row wise, column wise and the diagonal wise is same i.e. $$\frac{15}{11}$$. Hence, it is a magic square.
