Question

divide the sum 13/3and 6/7by the product of 2/7 and11/2

Answer 1

Sum of 13/3 and 6/7 = 13/3 + 6/7
                                   = 91/21 + 18/21 (Taking 21 as the LCM)
                                   = 109/21
Product of 2/7 and 11/2 = 2/7 * 11/2
                                   = 11/7    (2 gets cancelled out)
                  Division of the above acquired quantities :
                                   = 109/21 / 11/7
                                   = 109/21 * 7/11
                                   = 109/33 ( 7 gets cancelled out)

Answer 2

Sum of 13/3 &6/7= 91+18/21= 109/21.................. Product of 2/7 & 11/2= 22/14= 11/7............. Now , ATQ.... Divide the sum by product ===== 109/21÷11/7= 109/21×7/11 ( 21 gets cancelled by 7)........=109/3×1/11= 109/33= 3.3030303...
