Answer 1

Step-by-step explanation:

Correct Question:

In a "magic square", the sum of the numbers in each row, in each column and along the

diagonals is the same. Is this a magic square?

Solution:

(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.
