Question

1. Divide the sum of the rational numbers -5/7 and 11/3 by the difference of 6/13 and -17/5​

Answer 1

Answer:4030/5271

Step-by-step explanation:(i) -5/7 + 11/3               LCM=21

                                           = [3 x -5 + 7 x 11]/21 = [ -15 +77 ]/21 = 62/21

                                             (ii) 6/13 -(-17/5)= 6/13 + 17/5     LCM = 65

                                           = [ 5 x 6  + 13 x 17 ]/65 = [ 30 + 221 ]/65 = 251/65

                                          Therefore the required quotient=

                                             62/21 divided by 251/65

                                          = 62/21 x 65/251

                                          =   4030/5271
