Answer 1

Answer:

Step-by-step explanation:

the total for the two--------4/3 + 5/4 = 21/12

               percentage for a = (4/3)/ 21/12 x 100

                                               4/3 x 12/21 x 100

                                                 76%

                  percentage for a = (5/4)/ 21/12 x 100

                                               5/4 x 12/21 x 100

                                                     71%

                                                 76%-71% = 5%
