Question

Express each of the following rational numbers as the sum of an integer and a rational number: (i) 12/5
(ii) -11/7
(iii) -25/9
(iv) -103/20

Answer 1

Answer:(i)12/5= 2 + 2/5

             (ii)-11/7= -1 + (-4/7)

             (iii)-25/9 =  -2 + (-7/9)

              (iv) -103/20 = -5 + (-3/20)

Step-by-step explanation:(i)2 + 2/5 = [ 10 +2 ]/5 =12/5

                                             (ii) -1 + ( -4/7) = -1 -4/7 = [ -7 -4]/7 = -11/7

                                              (iii) -2 + (-7/9) = -2 -7/9 = [ -18 -7 ]/9 = -25/9

                                        (iv) -5 + (-3/20) = -5 - 3/20 = [ -100 -3]/20 = -103/20
