Question

4. In a magic square the sum of the numbers in each row, in
each column and along the diagonals is the same. Is it a
magic square?

4/11, 9/11, 2/11
3/11, 5/11, 7/11
8/11, 1/11, 6/11​

Answer 1

Step-by-step explanation:

(Along the first row 4/11 + 9/11 + 2/11 = 15/11)

Answer:

Sum of first row: 4/11 + 9/11 + 2/11 = 15/11 (Given)

Sum of second row: 3/11 + 5/11 + 7/11 = (3 + 5 + 7)/11 = 15/11

Sum of third row: 8/11 + 1/11 + 6/11 = (8 + 1 + 6)/11 = 15/11

Sum of first column: 4/11 + 3/11 + 8/11 = (4 + 3 + 8)/11 = 15/11

Sum of second column: 9/11 + 5/11 + 1/11 = (9 + 5 + 1)/11 = 15/11

Sum of third column: 2/11 + 7/11 + 6/11 = (2 + 7 + 6)/11 = 15/11

Sum of first diagonal (left to right): 4/11 + 5/11 + 6/11 = (4 + 5 + 6)/11 = 15/11

Sum of second diagonal (left to right): 2/11 + 5/11 + /11 = (2 + 5 + 8)/11 = 15/11

Since the sum of fractions in each row, in each column and along the diagonals is same, therefore it is a magic square.
