Question

divide the sum of 31 upon 9 and 5 upon 9 by their difference

Answer 1

firstly their sum is 31/9+5/9

36/9

=4

their difference is 31/9-5/9

now dividing their sum by their difference

=4/26/9

4*9/26

9/13

Answer 2

Their difference = 31/9 - 5/9

                            = 26/9

Divide = 36/9 ÷26/9

           =36/9 × 9/26
